comment: This subsumes all structuring relations used for LinguisticDataStructures. As a naming convention to distinguish relations in data structure from other relations, all names of dataStructuringRelations begin with 'has-'.
domain: LinguisticDataStructure

derivedForm
type: ObjectProperty
domain: Stem

directObject
type: ObjectProperty
sub property of: object
comment: A direct object is a grammatical relation that exhibits a combination of certain independent syntactic properties, such as the following: the usual grammatical characteristics of the patient of typically transitive verbs; particular case marking; a particular clause position; the conditioning of an agreement affix on the verb; the capability of becoming the clause subject in passivization; the capability of reflexivization. The identification of the direct object relation may be further confirmed by finding significant overlap with similar direct object relations previously established in other languages. This may be done by analyzing correspondence between translation equivalents [Crystal 1985, 94; Hartmann and Stork 1972, 155; Comrie 1989, 66; Andrews 1985, 68,120,126; Comrie 1985, 337].

CaseProperty
type: Class
subclass of: MorphosyntacticProperty
comment: CaseProperty is the class of properties that concern the grammatical encoding of a noun's relationship (syntactic or semantic) to some other element in the sentence, such as a verb, noun, pronoun, or adposition [Pei and Gaynor 1954, 35; Crystal 1980, 53-54; Anderson 1985, 179-180; Andrews 1985, 7172; Kuno 1973, 45; Blake 2001].

ModalityProperty
type: Class
subclass of: MorphosyntacticProperty
comment: ModalityProperty is the class of properties that concern the grammatical encoding of the status of the proposition itself, and not of the event to which the proposition refers, cf. AspectProperty [Palmer 2001, 1]. As a grammatical property, it represents those dimensions in the domains of knowledge (epistemic modality), social relations (deontic modality) and ability (abilitative modality), and possibly others.

VoiceProperty
type: Class
subclass of: MorphosyntacticProperty
comment: VoiceProperty is the class of properties that concern the grammatical encoding of the relationship between the verb and the nominals in a subject-predicate configuration. It selects a grammatically prominent syntactic constituent--subject--from the underlying semantic functions. In accusative language, the basic strategy is to select an agent as a subject [Shibatani 1988, 3]. It can be said that all voice systems mark the affectedness/nonaffectedness of sentential subjects [Klaiman 1988, 30]. Voice is also known as diathesis [Klaiman 1991,323].

PhoneticProperty
type: Class
subclass of: LinguisticProperty
comment: The class of properties used to describe speech sounds. The properties given here are more or less taken directly from Ladefoged's later works, in particular, the taxonomies of [Ladefoged 1997].

ForceProperty
type: Class
subclass of: MorphosyntacticProperty
comment: ForceProperty is the class of properties that concern the grammatical encoding of the speech act associated with a proposition. Among the traditionally defined values are Declarative, Imperative and Interrogative. Force is here distinguished from Mood, but there is a close association of Mood with Force values, e.g. between IndicativeMood and DeclarativeForce.

Predicator
type: Class
subclass of: PartOfSpeechProperty
comment: Predicator is the class of syntactic words that are fundamentally relation inducing. That is, predicators license argument structure [Anderson 1997, 14]. Verbs are quintessential predicators, though other categories, such as determiners and some nouns, are also predicative in nature.

Phrase
type: Class
subclass of: SyntacticConstruction
comment: Phrase is the class of syntactic constructions that consist of one or more syntactic words, but lack the subject-predicate organization of a clause. Phrases get their grammatical characteristics according to what word occupies the head position; thus, all phrases have heads [Crystal 1980, 232-233; Pei and Gaynor 1954, 169; Pike and Pike 1982, 453].

SubordinateClause
type: Class
subclass of: Clause
comment: SubordinateClause is the class of clauses that cannot stand on their own as sentences. A matrix clause combined with a subordinate clause form a main clause. In the sentence 'John thinks that Mary is sick', 'Mary is sick' is the subordinate clause.

Functor
type: Class
subclass of: PartOfSpeechProperty
comment: Functor is the class of syntactic word whose members are neither relation- nor argument-like non-relational [Anderson 1997, 20]. Typical functors include adpositions, subordinators, and complementizers.

SubordinatingConnective
type: Class
subclass of: Connective
comment: A subordinating connective is a connective that links constructions by making one of them a constituent of another. The subordinating conjunction typically marks the incorporated constituent [Crystal 1997, 370].

MorphologicalUnit
type: Class
subclass of: GrammarUnit
comment: MorphologicalUnit subsumes all grammatical units below the level of the syntactic word. Only a morphological unit may be a constituent of another morphological unit.

ArticulatoryProperty
type: Class
subclass of: PhoneticProperty
comment: The class of properties concerning how sounds are produced in the mouth.

AnteriorProperty
type: Class
subclass of: CoronalProperty
comment: Properties characterized by focusing on the upper passive articulator on the roof of the mouth [Ladefoged 1997, 597].

GenderProperty
type: Class
subclass of: MorphosyntacticProperty
comment: GenderProperty is the class of properties that are assigned to nouns on the basis of their inherent properties by an AssignmentSystem and required by the syntax to appear on the target in an AgreementSystem. Gender may but need not be assigned on the basis of sex [Corbett 1991].

CoronalProperty
type: Class
subclass of: BuccalProperty
comment: Properties of sounds produced with passive articulators lying on the coronal axis.

ApicalityProperty
type: Class
subclass of: CoronalProperty
comment: Properties characterized by focusing on the action of the lower, active articulator, ie which part of the tounge is used in articulation [Ladefoged 1997, 597].

StrictureProperty
type: Class
subclass of: MannerProperty
comment: Property of sounds produced by stricture of the vocal tract.

Determiner
type: Class
subclass of: PartOfSpeechProperty
comment: A Determiner is a part of speech whose members belong to a class of noun modifiers and express the reference, including quantity, of a noun [Crystal 1997,112].

MorphosemanticProperty
type: Class
subclass of: LinguisticProperty
comment: Linguistic properties having a semantic component.

GlottalTimingProperty
type: Class
subclass of: LaryngealProperty
comment: [Need a definition.]

EvidentialityProperty
type: Class
subclass of: MorphosyntacticProperty
comment: EvidentialFeature is the class of properties that concern the grammatical encoding of the speaker's belief in what they say. It is closely related to mood, some of whose values indicate the strength of the agent's belief.

HumanLanguageVariety
type: Class
subclass of: LinguisticSystem
comment: Human language variety is the class of all discrete entities (as identified by a linguist) that are considered systems of signs in their own right, emerge gradually as a cultural artifact, and are used by a particular community for communication.

SizeProperty
type: Class
subclass of: MorphosyntacticProperty
comment: SizeProperty is the class of properties that concern the grammatical encoding of relative size. Currently only Diminutive and Augmentative defined as possible properties. Typically, size is specified "derivationally" rather than by inflection.

Verbal
type: Class
subclass of: Predicator
comment: A Verbal is a part of speech whose members typically signal events and actions; constitute, singly or in a phrase, a minimal predicate in a clause; govern the number and types of other constituents which may occur in the clause; and, in inflectional languages, may be inflected for tense, aspect, voice, modality, or agreement with other constituents in person, number, or grammatical gender [Crystal 1997, 409; Givon 1984, 52; Payne 1997, 47].

BacknessProperty
type: Class
subclass of: DorsalProperty
comment: The class of properties describing sounds based on the relative horizontal position of the tongue. Note, Ladefoged refers to this property as Back.

DorsalProperty
type: Class
subclass of: BuccalProperty
comment: The class of properties associated with sounds made with the body of the tongue [Ladefoged 1997, 601]. Almost all vowels can be described using subclasses of this property.

GlottalStrictureProperty
type: Class
subclass of: LaryngealProperty
comment: [Need a definition.]

PlaceProperty
type: Class
subclass of: SupraLaryngealProperty
comment: The superclass of properties that specify the location of the articulators [Ladefoged 1997, 594].

Numeral
type: Class
subclass of: Quantifier
comment: A numeral is a partOfSpeech whose members function most typically as adjectives or pronouns and express a number, or relation to the number, such as one of the following: quantity, sequence, frequency, fraction [Hartmann and Stork 1972,155; Pei and Gaynor 1954,149].

MorphosyntacticProperty
type: Class
subclass of: LinguisticProperty
comment: MorphosyntacticFeature is the class of linguistic features that govern the grammatical behavior of morphosyntactic units. E.g., two morphosyntactic units can agree according to shared morphosyntactic features. Morphosyntactic features are also called grammatical categories. This class is intended to represent only the formal aspects of morphosyntax; that is, there is no notional component. In a grammatical system, such features occur in contrast to one another other, and are typically expressed in the same fashion [Crystal 1985, 43-44; Hopper, P. 1992, 81; Bybee 1985, 191].

DerivationalUnit
type: Class
subclass of: FunctionalUnit
comment: DerivationalUnit is the class of functional units whose members function to derive a new lexical unit from an existing one, by systematically changing the meaning and possibly altering the part of speech feature of the root or stem it attaches to [Hartmann and Stork 1972,62; Crystal 1985,89; Bybee 1985,81-82, 99].

LateralProperty
type: Class
subclass of: BuccalProperty
comment: Characterizing sounds involving air released through side of the mouth.

Abstract
type: Class
subclass of: Thing
comment: Any entity that does not occupy a position in space and time. See SUMO for a detailed explanation.

PartOfSpeechProperty
type: Class
subclass of: LinguisticProperty
comment: PartOfSpeechProperty is the class of all kind of parts of speech.

SyntacticConstruction
type: Class
subclass of: SyntacticUnit
comment: SyntacticConstruction is the class of grammar units that have syntactic structure, i.e., consisting of more than one syntactic word or construction in a syntactic configuration. [Crystal 1980, 85-86].

TenseProperty
type: Class
subclass of: MorphosemanticProperty
comment: Following [Comrie 1985, vii], we take tense to be the grammaticalisation of location in time. Tense Property is assigned to clauses on the basis of semantics: a tense value is selected for the clause from the range of tense values available in the given language. Tense Property is typically realised on the verb, but it may be found expressed multiply on different elements in the same clause. For example, tense may be found on more than one element of the verbal complex (e.g. in Kayardild [Evans 2003] or Paamese [Crowley 2002, 68], or on verbs as well as on certain spatial and temporal adverbs and certain prepositions in the same clause (e.g. in Malagasy [Randriamasimanana 1981, 355-367], [Keenan and Polinsky 1998, 566-567]. In the given language, the values of the Tense Property are assigned to the designated elements as a consequence of semantic choice, and all the available options of particular tense values expressing particular tense meanings can be described with a Tense Assignment System for that language. Since no languages have been found for which tense values are assigned by a Tense Distribution System (i.e. contextually, through agreement or government), Tense Property is not a Morphosyntactic Property. Instead, it is a Morphosemantic Property only.

Noun
type: Class
subclass of: PartOfSpeechProperty
comment: A noun is a broad classification of parts of speech usually identifying time-stable concept [Crystal 1997,371].

Adjectival
type: Class
subclass of: Predicator
comment: An adjectival, or 'adjective', is a part of speech whose members modify nouns. An adjectival specifies the attributes of a noun referent. Note: this is one case among many. Adjectivals are a class of modifiers. An adjectival may be inflected as comparitive or superlative [Crystal 1997,8; Payne 1997,63].

AspectProperty
type: Class
subclass of: MorphosemanticProperty
comment: The term 'aspect'; designates the perspective taken on the internal temporal organisation of the event, and different values of the Aspect Feature distinguish different ways of viewing the internal temporal constituency of the same event [Comrie 1976, 3ff], after [Holt 1943, 6; Bybee 2003, 157]. The 'event is understood here as a general term covering any situation type (a state, activity, accomplishment, achievement, etc.) as expressed by the verb phrase of the construction. Unlike Tense Feature, which expresses event-external time and is deictic, Aspect Feature is event-internal and non-deictic, as it is not concerned with relating the time of the event to any other time point. Aspect Property is assigned to clauses on the basis of semantics: an aspect value is selected for the clause from the range of aspect values available in the given language. Aspect Property is typically realised on the verb, but it may be found expressed multiply on different elements in the same clause. It may be found on more than one element of the verbal complex, or on verbs as well as certain adverbs in the same clause. In the given language, the values of the Aspect Property are assigned to the designated elements as a consequence of semantic choice, and all the available options of particular aspect values expressing particular aspect meanings can be described with an Aspect Assignment System for that language. Since no languages have been found for which aspect values are assigned by an Aspect Distribution System (i.e. contextually, through agreement or government), Aspect Feature is not a Morphosyntactic Property. Instead, it is a Morphosemantic Property only. NOTE: Although the semantic basis for the Aspect Property are the distinctions identified in the internal temporal constituency of an event, aspect meanings frequently combine with tense, modal or other meanings expressing actionality distinctions. Hence, markers expressing aspect values are frequently portmanteaux realising …

FeatureSpecification
type: Class
subclass of: LinguisticDataStructure
comment: A FeatureSpecification is a data structure that groups together a linguistic feature with a value [Maxwell, Simons, and Hayashi 2000].

LabialProperty
type: Class
subclass of: PlaceProperty
comment: The class of properties associated with characteristics of labial articulations [Ladefoged 1997, 594].

CoordinatingConnective
type: Class
subclass of: Connective
comment: A coordinating connective is a connective that links constituents without syntactically subordinating one to the other [Crystal 1997,93].

Segment
type: Class
subclass of: FormUnit

LinguisticTaxon
type: Class
subclass of: Taxon
comment: LinguisticTaxon is the class of Taxons whose instances are used in the scientific classification language varieties. That is, instances of LinguisticTaxon have instances that are human language varieties.

Connective
type: Class
subclass of: Functor
comment: Also known as a conjunction, a Connective is a class of parts of speech whose members syntactically link words or larger constituents, and expresses a semantic relationship between them. A conjunction is positionally fixed relative to one or more of the elements related by it, thus distinguishing it from constituents such as English conjunctive adverbs [Crystal 1997, 81].

BuccalProperty
type: Class
subclass of: PlaceProperty
comment: A subclass of place Properties roughly referring to positions inside the mouth [Ladefoged 1997, 606].

Article
type: Class
subclass of: Determiner
comment: An article is a member of a small class of determiners that identify a noun's definite or indefinite reference, and new or given status [Crystal 1997,26].

Pronominal
type: Class
subclass of: ProForm
comment: A Pronoun is a ProForm which functions like a noun and substitutes for a noun or noun phrase [Crystal 1997,312].

FunctionalUnit
type: Class
subclass of: MorphologicalUnit
comment: FunctionalUnit is the class of units that includes inflectional and derivational units. Functional units attach to roots and stems and can be used to form morphological paradigms in a grammatical description.

OrthographicPart
type: Class
subclass of: WrittenLinguisticExpression
comment: An OrthographicPart is a unit of an orthography that is not orthographically independent, that is, not necessarily able to stand alone as an orthographic word set off by whitespace. In the printed instance of the word 'conceive', 'eive' is an instance of orthographic part. Note that an orthographic part is not the same as a single glyph, although, some orthogrpaphic parts are single glyphs.

GeneticTaxon
type: Class
subclass of: LinguisticTaxon
comment: GeneticTaxon is the class of all taxons whose members are based on genetic relatedness.

LinguisticProperty
type: Class
subclass of: Abstract
comment: LinguisticProperty is the class of properties that pertain to linguistic units. A unit's properties determine its behavior in a grammatical system.

Among the traditionally defined properties are Declarative, Imperative and Interrogative. These are a somewhat mixed bag of attitude (e.g. optative, volitive, subjunctive) and speech-act (e.g. imperative, commissive) values.

Clitic

comment: A SemanticUnit is the class of semantics elements, or units of semantic structure (sometimes called a sememe). Semantic units serve as the meaning component of linguistic signs. A semantic unit is intended for linguistic description and no particular logical representation is implied.

Glyph
type: Class
subclass of: OrthographicPart
comment: A Glyph is a symbol used in a writing system to represent some kind of linguistic unit, such as a single sound, a phoneme or an entire word. Glyphs are concatenated in a writing system to form orthographic parts and orthographic words. Consider the printed word 'apple'. This word contains two instances of the 'p' glyph, which is a subclass of Glyph. Instances of a Glyph share a similar shape and can be called 'shapemes'. The class Glyph is not the same as Grapheme. A Grapheme is a contrastive unit within a particular writing system. The notion of a glyph is relevant across writing systems. For instance, consider the symbol 'р' used in a printed instance of a Russian word 'русский'. Now consider the symbol 'p' used in the printed instance of an English word 'pickle'. Both symbols are instances of the same Glyph. They share the same general shape, but do not have the same phonemic value.

ContinuousAspect
type: Class
subclass of: AspectProperty
comment: A value of Aspect Property assigned to the designated element in the clause when the meaning selected for the clause is that which indicates that the situation spoken about has internal temporal structure, but the situation cannot be regarded as habitual (i.e. it cannot be regarded as a characteristic feature of a whole period). Hence, continuousness can be defined negatively as imperfectivity that is not habituality [Comrie 1976, 26-32], and it can be regarded as a sub-type of imperfectivity. Typically, for an aspect value to be labelled as Continuous, the aspectual meaning has to minimally express continuousness, although it may additionally express other temporal, aspectual, or modal meanings, or actionality distinctions. Continuous aspectual meaning can be further subdivided into two types: progressive meaning and nonprogressive meaning. These two aspectual meanings may or may not be grammaticalised as separate aspect values.

ErgativeCase
type: Class
subclass of: CaseProperty

type: Class
subclass of: CaseProperty
comment: EssiveCase expresses that the referent of the noun it marks is the location at which another referent exists [Lyons 1968, 299,301; Crystal 1985, 112; Blake 2001].

ExistentialMarker
type: Class
subclass of: Verbal
comment: An existential marker is a syntactic category whose members are found in distinct clause types and which mark a referent's existence [Crystal 1997,142].

Expletive
type: Class
subclass of: PartOfSpeechProperty
comment: An expletive (also known as a dummy word) is a part of speech whose members have no meaning, but complete a sentence to make it grammatical [Crystal 1997,127;].

comment: ExtinctVariety is the class of human language varieties that no longer have native speakers, e.g., Frankish or Mozarabic.

FeatureAgreementSystem
type: Class
subclass of: FeatureDistributionSystem
comment: A type of FeatureDistributionSystem; in a given language, it is the system according to which feature values (of a particular feature) are determined for elements through agreement (i.e. where the form of the element is determined by the presence of another element).

FeatureConstraint
type: Class
subclass of: LinguisticDataStructure
comment: A FeatureConstraint is a LinguisticDataStructure which groups a part of speech value with a set of features. Within a FeatureSystem of some language, it indicates which Features may be associated with a particular linguistic unit based on the unit's part of speech.

FeatureGovernmentSystem
type: Class
subclass of: FeatureDistributionSystem
comment: A type of FeatureDistributionSystem; in a given language, it is the system according to which feature values (of a particular feature) are determined for elements through government (i.e. where the form of the element is determined by the presence of another element).

FeatureStructure
type: Class
subclass of: LinguisticDataStructure
comment: A FeatureStructure is a set of one or more FeatureSpecifications. A FeatureStructure is a kind of information structure, a container or data structure, used to group together qualities or features of some object. In a grammatical feature system, a FeatureStructure holds the grammatical information associated with some linguistic unit. In a typed feature system, a FeatureStructure has an associated type, usually a PartOfSpeech. [Shieber 1986; Maxwell, Simons, and Hayashi 2000].

FeatureSystem
type: Class
subclass of: LinguisticDataStructure
comment: A 3-tuple: (1) a set of FeatureValues, (2) the particular FeatureAssignmentSystem according to which the values are assigned inherently to elements in the given language, and (3) the particular FeatureDistributionSystem according to which the values are determined contextually for elements in the given language. The class of grammatical opposition sets relevant for a specific domain (tense, aspect, number, etc.) in a given language.

FeminineGender
type: Class
subclass of: GenderProperty
comment: A gender property established on the basis of agreement, to which nouns may be assigned if 1) they inherently denote females. Additionally, but not necessarily, nouns may be assigned this value if: 2) their formal properties (morphological or phonological) lead them to be assigned to the same agreement pattern as other nouns within the language that have female denotation. 3) they are arbitrarily assigned to the same agreement pattern as other nouns in the language that have female denotation [Corbett 1991].@en

FirstPerson
type: Class
subclass of: PersonProperty
comment: First is a person property that refers minimally to the speaker. It may also refer to the speaker combined with either the addressee or the non-participant or both, allowing for the following subdivisions: a) first person b) first person inclusive c) first person exclusive [Cysouw 2003].

FirstPersonExclusive
type: Class
subclass of: PersonProperty

FirstPersonInclusive
type: Class
subclass of: PersonProperty

FocusAntipassiveVoice
type: Class
subclass of: VoiceProperty
comment: Blocks the P or logical object (basic absolutive) nominal from being assigned Focus salience. Topic salience is available for assignment to various arguments, including the P, but Focus salience is always assigned to A, and is therefore inaccessible to P or any other nominal. [Klaiman 1991, 236]

FutureInFutureTense
type: Class
subclass of: TenseProperty
comment: FutureInFutureTense locates the situation in question in the future, relative to a temporal reference point that itself is located in the future relative to the moment of utterance [Comrie 1985, 128].

FutureInPastTense
type: Class
subclass of: TenseProperty
comment: FutureInPastTense locates the situation in question in the future, relative to a contextually determined temporal reference point that itself must be located in the past relative to the moment of utterance [Comrie 1985, 128].

FuturePerfectTense
type: Class
subclass of: TenseProperty
comment: Describes an event that occurs after the time of speaking but before some reference point in time which also occurs after the time of speaking. This is also known as PastInFutureTense. [Comrie 1985, 126]

FutureTense
type: Class
subclass of: TenseProperty
comment: A value of Tense Property assigned to the designated element in the clause when the meaning selected for the clause is that intended to locate the event spoken about as posterior to the deictic centre of the utterance. Most commonly, this tense meaning is referred to as 'future', because in absolute tense systems the deictic centre is the moment of speech. However, in relative tense systems, where the deictic centre can be moved to any point on the time line, it is more appropriate to refer to this temporal relation as 'posterior'. The posterior temporal relation may obtain either in 'simple' or 'perfect' contexts. Modelling of this distinction originates from [Reichenbach 1947], who suggested using a third point in time, 'reference point', to capture all possible tense distinctions. In all 'simple' temporal relations, the reference point coincides with the location of the event spoken about. 'Perfect' tense meanings are created when the reference point is separated and moved away from the event time, thus altering the viewing of the temporal location of the event even though the event's actual location with respect to the deictic centre remains the same. Posterior temporal relationships obtaining in a 'perfect' context occur when the reference point is moved away from the event time. There are various logical possibilities for locating the reference point with respect to the other two points, though none of them seem to be typically grammaticalised as separate tenses. Typically, for a tense value to be labelled as Future Tense, the tense meaning has to minimally express the posterior temporal relationship, although it may additionally express other temporal, aspectual, or modal meanings.

GeneralNumber
type: Class
subclass of: NumberProperty

GenitiveCase
type: Class
subclass of: CaseProperty
comment: GenitiveCase is used to mark the noun whose referent is the possessor of the referent of another noun [Crystal 1980, 161; Hartmann and Stork 1972, 9495,180; Pei and Gaynor 1954, 82,172; Anderson 1985, 185; Fleming 1988, 10].

GlottalMovementProperty
type: Class
subclass of: LaryngealProperty
comment: [Need a definition.]

Grapheme
type: Class
subclass of: FormUnit
comment: A Grapheme is the smallest meaningful contrastive unit in a writing system. A grapheme is an abstraction over a set of like glyphs, the actual images on the page. That is, a particular grapheme is realized by particular glyphs. More than one glyph can realize the same grapheme. For instance, the letter A and its cursive equivalent are each realizations of the grapheme Latin Captial Letter A.

GreaterPaucalNumber
type: Class
subclass of: NumberProperty
comment: GreaterPaucal is a number property that quantifies the denotation of the nominal element so that it specifies that there are a small number of distinct entities, greater than paucalNumber but less than pluralNumber (so semantically similar to 'several' in English). Ln An example of greaterPaucalNumber is found in Sursurunga (sgz): Ln Gamhat til main gam han suri tártár Ln 2.GRPAU from here 2.PL go PURPOSE chop Ln on á kakau káián Himaul viles, honin Ln it TOPIC cacao its Himaul village today Ln dilhat má lu tangkabin sirai má ... Ln 3.GRPAU EMPHATIC HABITUAL begin selling now Ln "You all from here (i.e. from this village) went to slash (for burning then planting) Himaul village's cacao, which already they (i.e. people from Himaul) have begun to sell ..." Hutchisson uses the term 'quadral' for Greater Paucal; see the terminology notes for a comment on this [Corbett 2000: 28].

subclass of: NumberProperty
comment: GreaterPlural

GreaterPluralNumber
type: Class
subclass of: NumberProperty
comment: GreaterPlural is a number property that expresses (a) the fact that there is an excessive number of events or entities denoted by the noun or nominal element, or (b) the fact that the noun or nominal denotes all possible instances.

Group
type: Class
subclass of: SyntacticConstruction
comment: Group is the class of syntactic constructions intermediate between the level of word and phrase.

HabitualAspect
type: Class
subclass of: AspectProperty
comment: A value of Aspect Property assigned to the designated element in the clause when the meaning selected for the clause is that which indicates that the situation spoken about is characteristic of an extended period of time --- so extended that the situation is viewed as characteristic of the whole period. The decision that a situation is characteristic of an extended period of time is not in itself linguistic, but once it has been made, an explicitly habitual form can be used to describe it. Note that the classification of a situation as characteristic of a period of time is not derived directly from the comparison of their length or frequency; hence, the situation may be objectively either long or short, and either frequent or infrequent, with respect to the period it characterises. This is because the way we choose to characterise can ivolve a component which is objectively small in relation to the whole. Typically, for an aspect value to be labelled as Habitual, the aspectual meaning has to minimally express habituality, although it may additionally express other temporal, aspectual, or modal meanings, or actionality distinctions. Habituality can in principle be combined with any other semantic aspectual values appropriate to situations that can be protracted in time or iterated [Comrie 1976, 26-32]. Since habituality is concerned with the internal temporal structure of the (extended) event, it can be regarded as a sub-type of imperfectivity.

HearsayEvidentiality
type: Class
subclass of: EvidentialityProperty
comment: HearsayEvidentiality, also called third hand, encodes the fact that the speaker came to believe the content of the expression from a source generally considered less reliable than with a SecondHandEvidential [Palmer 2001, 40].

HesternalPastTense
type: Class
subclass of: TenseProperty
comment: HesternalPastTense locates the situation in question somewhere in the span beginning with the period defined culturally as 'yesterday' and extends back through some period that is considered nonremote [Comrie 1985,87-88; Dahl 1985,126].

subclass of: HeightProperty
comment: Characterizing sounds produced with the tongue near the top of the mouth.

HodiernalFutureTense
type: Class
subclass of: TenseProperty
comment: HodiernalFutureTense locates the situation in question after the moment of utterance within the span culturally defined as 'today' [Comrie 1985, 86; Bybee, Perkins and Pagliuca 1994, 247].

HodiernalPastTense
type: Class
subclass of: TenseProperty
comment: HodiernalPastTense locates the situation in question before the moment of utterance within the span culturally defined as 'today' [Comrie 1985,87; Dahl 1985,125-126]. Contrasts with PreHodiernalPastTense.

ImmediateFutureTense
type: Class
subclass of: TenseProperty
comment: ImmediateFutureTense, also called 'close future', locates the situation in question shortly after the moment of utterance [Dahl 1985,121; Comrie 1985,94; Bybee, Perkins, and Pagliuca 1994, 244-245).

ImperativeForce
type: Class
subclass of: ForceProperty
comment: [Need comment]

ImperfectiveAspect
type: Class
subclass of: AspectProperty
comment: A value of Aspect Property assigned to the designated element in the clause when the meaning selected for the clause is that which indicates that the event spoken about is to be looked at from inside, from within its temporal boundaries; imperfective aspect is crucially concerned with the internal temporal structure of the event [Comrie 1976, 16ff]. Typically, for an aspect value to be labelled as Imperfective, the aspectual meaning has to minimally express the imperfective viewpoint, although it may additionally express other temporal, aspectual, or modal meanings, or actionality distinctions. Imperfective aspectual meaning can be further subdivided into two types: habitual meaning and continuous meaning. These two aspectual meanings may or may not be grammaticalised as separate aspect values.

ImpersonalPassiveVoice
type: Class
subclass of: VoiceProperty
comment: A Passive that alters the mapping of a nominal to the Subject relation in a basic intransitive structure [Klaiman 1991,23]

InablativeCase

subclass of: AspectProperty
comment: InceptiveAspect, also called the ingressive, encodes the beginning portion of some event [Bybee 1985, 147, 149; Payne 1997, 240; Bhat 1999,176].

IncorporatingAntipassiveVoice
type: Class
subclass of: VoiceProperty
comment: Blocks the P or logical object (basic absolutive) nominal from being assigned Focus salience. This correlates with the P's morphosyntactic downgrading, whereby it becomes insusceptible to any informational salience assignment. [Klaiman 1991,236]

IndefiniteArticle
type: Class
subclass of: Article
comment: An article is a part of speech whose members are used to refer to an entity (or class of entities) which is not capable of specific identification [Crystal 1997, 193].

Infix
type: Class
subclass of: Affix

InflectionalUnit
type: Class
subclass of: FunctionalUnit
comment: InflectionalUnit is the class of functional units whose members designate such grammatical categories as tense, aspect, mood etc. The various forms of an InflectionalUnit plus the stem forms a grammatical paradigm and express a grammatical contrast that is obligatory for its stem's part of speech in some given grammatical context. An inflectional unit does not alter the part of speech feature of the root or stem it attaches to. It is typically located farther from its Root than a derivational unit and produces a predictable, nonidiosyncratic change of meaning [Crystal 1980,184; Hartmann and Stork 1972,112; Bybee 1985,2, 99].

InformationalForce
type: Class
subclass of: ForceProperty

InteressiveCase
type: Class
subclass of: CaseProperty
comment: InteressiveCase expresses that the referent of the noun it marks is the location between which another referent exists. It has the meaning of 'between'.

Interjection
type: Class
subclass of: PartOfSpeechProperty
comment: An interjection is a part of speech, typically brief in form, such as one syllable or word, whose members are used most often as exclamations or parts of an exclamation. An interjection, typically expressing an emotional reaction, often with respect to an accompanying sentence, is not syntactically related to other accompanying expressions, and may include a combination of sounds not otherwise found in the language [Crystal 1997,200].

InterlativeCase

comment: Interlinear glossed text (IGT) is a linguistic data structure meant to display morphosyntactic structure: morphemes, morpheme boundaries, morpheme types (clitics, prefixes, reduplicated forms), morphosyntactic features/values and part of speech information. At a minimum, an instance of IGT includes a single line of source language followed by a translation line. Often, a second gloss line is included to show detailed morphosyntactic structure using both words and phrases from the target language and various labels, or 'grams', that indicate morphosyntactic features/values, etc. It is possible to include separate lines for the orthographic form, phonetic form, and phonological form. Standards for IGT include the Leipzig Glossing Rules.

IntertranslativeCase
type: Class
subclass of: CaseProperty
comment: IntertranslativeCase expresses the notion of something moving along a trajectory between the referent of the noun it marks. It has the meaning 'along the in between'.

IntransitiveVerb

IterativeAspect
type: Class
subclass of: AspectProperty
comment: IterativeAspect, also called repetitives, encodes a number of events of the same type that are repeated on a particular occasion. The time interval which is relevant to the iterative is relatively shorter than in the case of the habitual [Bybee 1985, 150; Bybee, Perkins and Pagliuca 1994, 127]. Portrays events repeated on the same occasion (like the iterative knocking on the door) [Bhat 1999, 53]

comment: Characterizing sounds produced by the blade of the tongue [Ladefoged 1997, 596].

Language
type: Class
subclass of: GeneticTaxon
comment: The concept of a language is very difficult to define axiomatically. Here, we say that a language is a subclass of GeneticTaxon above the level of dialect. Language, in this sense, is often defined according to mutual intelligibility among its speakers, when the speakers of the language are located in the same general location, the sharing of a common writing system, or the sharing of a common literature.

LanguageFamily

LanguageSubfamily
type: Class
subclass of: GeneticTaxon
comment: LanguageSubfamily is a grouping of languages defined more narrowly than a LanguageFamily. In a given Subfamily, all languages are genetically related and are instances of the same LanguageFamily. For there to be a subfamily, there must be a family.

Ligature
type: Class
subclass of: Glyph
comment: A Ligature is a special type of glyph composed by two or more basic glyphs fused together as a single symbol.

LinguisticSign
type: Class
subclass of: Abstract
comment: A linguistic sign is an abstract structure whose instances participate in a linguistic system, or language. By definition, a linguistic sign must have a form component (whose elements are phonological units), a grammatical component (whose elements are grammatical units), and a meaning component (whose elements are semantic units). The formal structure of a linguistic sign is determined by the grammar of a language. The information value of a linguistic sign, its meaning, is not fixed, but determined by the conventions of the language. The relation of form to meaning is largely arbitrary within a semiotic system. Signs are classified primarily according to what kinds of formal relations they participate in, and, secondly, according to their complexity (whether they are atomic or composed of other signs). Signs range from morphological and syntactic constructions to whole discourse segments [de Saussure 1983; Hervey 1979; Pollard and Sag 1994].

MainClause
type: Class
subclass of: Clause
comment: MainClause is the class of clauses that can stand on their own as a full, independent sentence. If a sentence contains any embedded clauses, the main clause is understood as the matrix plus the embedded clauses. In the sentence 'John thinks that Mary is sick', 'John thinks that Mary is sick' is the main clause [Crystal 2001, 231].

comment: A construction that expresses the contradiction of some or all of a proposition [Crystal 1980, 257]. Note: this value is not to be confused with the notion "Negative Polarity Item", which is an expression that occurs in the scope of Negation (i.e. Negative Polarity).

NeuterGender
type: Class
subclass of: GenderProperty
comment: A gender property established on the basis of agreement, to which nouns may be assigned, either by a semantic rule, if they belong to the semantic residue of the assignment system, or by a formal rule, if assignment depends on inflectional class membership. Typically, this means that the neuter gender may cover some inanimates and possibly some portion of lower order animates. Note: Although in familiar Indo-European languages the term neuter gender may be part of a system with three or less values, it can be used for systems containing more than three gender values (e.g. Bininj Gunwok).

NonProgressiveAspect
type: Class
subclass of: AspectProperty
comment: A value of Aspect Property (also stative aspect) assigned to the designated element in the clause when the meaning selected for the clause is that which indicates that the situation spoken about has internal temporal structure, it cannot be regarded as habitual, but is regarded as a continuing state. Hence, Nonprogressive Aspect can be regarded as a sub-type of continuousness (which, in turn, is a sub-type of imperfectivity). Since languages have different criteria for classifying predicates as stative or not, they may have different rules for determining when explicitly nonprogressive (i.e. explicitly stative) forms can be used. Typically, for an aspect value to be labelled as Nonprogressive, the aspectual meaning has to minimally express nonprogressiveness, although it may additionally express other temporal, aspectual, or modal meanings, or actionality distinctions.

This case may be found in items such as the following: existential clauses, nouns that are accompanied by numerals or units of measure, or predications of material from which something is made. It often has a meaning similar to the English word 'some' [Pei and Gaynor 1954, 161; Richards, Platt, and Weber 1985, 208; Quirk, et al. 1985, 249; Sebeok 1946, 1214].

subclass of: TenseProperty
comment: Locates the situation in question in the future, prior to a reference time in the future. Also called PastInPast tense.

PastTense
type: Class
subclass of: TenseProperty
comment: A value of Tense Property assigned to the designated element in the clause when the meaning selected for the clause is that intended to locate the event spoken about as anterior to the deictic centre of the utterance. Most commonly, this tense meaning is referred to as 'past', because in absolute tense systems the deictic centre is the moment of speech. However, in relative tense systems, where the deictic centre can be moved to any point on the time line, it is more appropriate to refer to this temporal relation as 'anterior'. The anterior temporal relation may obtain either in 'simple' or 'perfect' contexts. Modelling of this distinction originates from [Reichenbach 1947], who suggested using a third point in time, 'reference point', to capture all possible tense distinctions. In all 'simple' temporal relations, the reference point coincides with the location of the event spoken about. 'Perfect' tense meanings are created when the reference point is separated and moved away from the event time, thus altering the viewing of the temporal location of the event even though the event's actual location with respect to the deictic centre remains the same. A common instance of an anterior temporal relationship obtaining in a 'perfect' context occurs when the reference point is moved away from the event time and located instead at the moment of speech. The event time is still anterior to the moment of speech, but it is viewed against a stretch of time which began at the event and continues up to the moment of speech --- e.g. the English I have read this book, I have seen John --- hence the interpretation that the event has an effect or is in some way still relevant at the moment of speech. In some languages (e.g. English) this tense meaning is labelled as (one of the uses of the) Present Perfect, in others (e.g. Polish) this meaning may be collapsed with the 'simple' anterior meaning and labelled simply as Past. Typically, for a tense value to be labelled as Past Tense, th…

comment: An evaluative property of a noun that indicates the speaker regards the person or object being referred to with distaste, contempt, or displeasure [Valentine 2001, 190-193].

PerfectTense
type: Class
subclass of: TenseProperty
comment: A value of Tense Feature assigned to the designated element in the clause when the meaning selected for the clause is that intended to locate the event spoken about as anterior, simultaneous, or posterior to the deictic centre of the utterance, and additionally the reference point from which this event is viewed is separated and moved away from the event time. This alters the viewing of the temporal location of the event even though the event's actual location with respect to the deictic centre remains the same. 'Perfect' temporal relations contrast with 'simple' temporal relations in which the reference point coincides with the location of the event spoken about. Modelling of this distinction originates from [Reichenbach 1947]. There are two types of 'perfect' context which may lead to separate tense values: (1) The first type occurs when the reference point is moved away from the event time and instead located after the event time. A common example occurs with an anterior temporal relationship, when the reference point is moved from the event time to the moment of speech. The event time is anterior to the moment of speech, but it is viewed against a stretch of time which began at the event and continues up to the moment of speech --- e.g. the English I have read this book, I have seen John --- hence the interpretation that the event has an effect or is in some way still relevant at the moment of speech. [Note that in some languages (e.g. English) this tense meaning is labelled as (one of the uses of the) Present Perfect, in others (e.g. Polish) this meaning may be collapsed with the 'simple' anterior meaning and labelled simply as Past.] The interpretation of this type of the perfect often includes at least two related but distinguishable uses: the resultative perfect (Someone has stolen my purse) and the experiential perfect (I have read this book before) [Dahl and Velupillai 2005,271]. (2) The second type occurs when the reference point is moved away from the ev…

PerfectiveAspect
type: Class
subclass of: AspectProperty
comment: A value of Aspect Property assigned to the designated element in the clause when the meaning selected for the clause is that which indicates that the event spoken about is to be viewed as a bounded whole, looked at from outside, without necessarily distinguishing any of its internal structure [Comrie 1976,16ff). Typically, for an aspect value to be labeled as Perfective, the aspectual meaning has to minimally express the perfective viewpoint, although it may additionally express other temporal, aspectual, or modal meanings, or actionality distinctions.

PhasalAspect
type: Class
subclass of: AspectProperty
comment: A set of aspectual distinctions involving relations between a background situation (the reference situation) and a situation located relative to the reference situation (the denoted situation). In English, phasal distinctions are expressed by auxiliary-headed constructions, like the inceptive, progressive, and perfect constructions, whose head verbs express the aspectual class of the denoted situation. The aspectual class of the denoted situation differs from that of the reference situation [Michaelis 1998,xv]. An event may have a beginning and an end, a middle portion (continuing or changing), and also an ensuing result or an altered state. These are considered to be the various "phases" of an event. A speaker may talk about an event from the point of view of any of these individual phases, and his language may have inflectional (or other type of) markers for representing these distinctions. Since such markers indicate distinctions in the temporal structure of an event, we may regard them as belonging to the category of aspect. It has been suggested [Dik 1989, 186] that these may be grouped under a subcategory (or "level") of aspect called "phasal aspect". [Bhat 1999,49]

PluralNumber
type: Class
subclass of: NumberProperty
comment: PluralNumber is a number property that quantifies the denotation of the nominal element so that: 1) it specifies that there are more than one. In this English example below, plural is shown by both the noun and the verb in (2): (1) my dog watches television (2) my dogs watch television [Corbett 2000: 5] 2) additionally, but not necessarily, pluralNumber may be assigned on the basis of formal properties (e.g. pluralia tantum, or measles / *measle). 3) if pluralNumber functions as generalNumber, it may specify a lack of commitment with regard to quantification ([Corbett 2000,17] notes this system does not exist in pure form, that is, no language employs it as the normal case). Some Cushitic languages, generalNumber can be the same as singularNumber for some nouns, but the same as pluralNumber for other nouns. For example, in Arbore (arv), generalNumber may contrast with the singular in the absence of a distinct plural form: Ln Singular Ln tiis-in 'a maize cob' Ln lasa-n 'a loaf' nebel-in 'a cock ostrich' ln General ln tíise 'maize cob(s)' ln lássa 'bread' ln nebel 'ostrich(es)' ln [Corbett 2000: 17-18]

PresentPerfectTense
type: Class
subclass of: TenseProperty
comment: The simultaneous temporal relation may obtain either in 'simple' or 'perfect' contexts. Modelling of this distinction originates from [Reichenbach 1947], who suggested using a third point in time, 'reference point', to capture all possible tense distinctions. In all 'simple' temporal relations, the reference point coincides with the location of the event spoken about. 'Perfect' tense meanings are created when the reference point is separated and moved away from the event time, thus altering the viewing of the temporal location of the event even though the event's actual location with respect to the deictic centre remains the same. A common instance of a simultaneous temporal relationship obtaining in a 'perfect' context occurs when the reference point is moved away from the event time and located instead before the moment of speech. The event time is still simultaneous with the moment of speech, but it is viewed against a stretch of time which began at the reference point and continues up to the moment of speech --- e.g. the English I have lived here [for ten years] --- hence the interpretation that the event which began in the past extends up to the moment of speech. In some languages (e.g. English) this tense meaning is labelled as (one of the uses of the) Present Perfect, in others (e.g. Polish) this meaning may be collapsed with the 'simple' simultaneous meaning and labelled simply as Present.

PresentTense
type: Class
subclass of: TenseProperty
comment: A value of Tense Property assigned to the designated element in the clause when the meaning selected for the clause is that intended to locate the event spoken about as simultaneous with the deictic centre of the utterance. Most commonly, this tense meaning is referred to as 'present', because in absolute tense systems the deictic centre is the moment of speech. However, in relative tense systems, where the deictic centre can be moved to any point on the time line, it is more appropriate to refer to this temporal relation as 'simultaneous'. It is important to note --- for all tense values, but in particular for the Present Tense --- that the 'times' which are used to locate the event, the deictic centre, and the reference point, may or may not be 'points' on the time line. Conventionally, these concepts are considered neutral with regard to whether they are points or intervals of time longer than a point. In a formal model of tense meanings they could, for example, be represented as sets (of points): in order to capture temporal distinctions, the notion of an event being 'simultaneous with the moment of speech', may be understood as (the set of) event time (points) and (the set of) speech time (points) having a non-empty intersection. Hence, this semantic model of the Present Tense value may include the interpretation of the present as 'universal' or 'generic'. The simultaneous temporal relation may obtain either in 'simple' or 'perfect' contexts. Modelling of this distinction originates from [Reichenbach 1947], who suggested using a third point in time, 'reference point', to capture all possible tense distinctions. In all 'simple' temporal relations, the reference point coincides with the location of the event spoken about. 'Perfect' tense meanings are created when the reference point is separated and moved away from the event time, thus altering the viewing of the temporal location of the event even though the event's actual location with respect to the deictic ce…

ProgressiveAspect
type: Class
subclass of: AspectProperty
comment: A value of Aspect Property (also called Nonstative aspect) assigned to the designated element in the clause when the meaning selected for the clause is that which indicates that the situation spoken about has internal temporal structure, it cannot be regarded as habitual, and reference is made to this situation in progress. Hence, progressiveness can be defined as the combination of progressive meaning with nonstative meaning, and it can be regarded as a sub-type of continuousness (which, in turn, is a sub-type of imperfectivity). Since languages have different criteria for classifying predicates as stative or not, they may have different rules for determining when explicitly progressive forms can be used. Typically, for an aspect value to be labelled as Progressive, the aspectual meaning has to minimally express progressiveness, although it may additionally express other temporal, aspectual, or modal meanings, or actionality distinctions.
