While this phenomenon (referred to as multiple (or extended) exponence in the morphological literature) has been examined within the context of morphological theory and diachronic research, little work has investigated the processing of morphological redundancy and synchronic motivations for its use. This paper reports a field speech-in-noise experiment to assess perceptual functionality of redundant markers in an agglutinating, morphologically complex language of Northern Mexico, Choguita Rarámuri (Tarahumara). This language possesses morphological patterns in which a meaning is redundantly cued by two consecutive suffixes, and where the second (outer) suffix is optional. We show that the effect of adding the optional suffix varies with the overall likelihood of recognising its meaning in context: cue redundancy helps when recognition of the cued meaning is difficult but hurts when recognition of the cued meaning is easy. The results are interpreted as support for the operation of Grice's Maxim of Clarity in spoken word recognition and/or production: the listener expects the speaker to say only as much as is necessary to transmit the message.
