Etymology 1

edit

From Middle English ratte, rat, rotte, from Old English rætt, from Proto-West Germanic *ratt, from Proto-Germanic *rattaz, *rattō (compare West Frisian rôt, Dutch rat), of uncertain origin, possibly from Proto-Indo-European *reh₁d- (“to scrape, scratch, gnaw”). However, the rat may have been unknown in Northern Europe in antiquity, and the Proto-Germanic word may have referred to a different animal; see *rattaz for more.[1] Attestation of this family of words begins in the 12th century. (Can this(+) etymology be sourced?)

Some of the Germanic cognates show considerable consonant variation, e.g. Middle Low German ratte, radde; Middle High German rate, ratte, ratze.[1] The irregularity may be symptomatic of a late dispersal of the word, although Kroonen accounts for it with a Proto-Germanic stem *raþō nom., *ruttaz gen.,[1] showing both ablaut and a Kluge's law alternation, with the variation arising from varying remodellings in the descendants. Kroonen states that this requires a Proto-Indo-European etymon in final *t and is incompatible with the usual derivation from Proto-Indo-European *reh₁d- (“to scrape, scratch, gnaw”).[1]
