The phonological and grammatical status of Murui ‘word’

Different sorts of phonological and grammatical criteria can be used to identify wordhood in Murui, a Witotoan language from Northwest Amazonia. A phonological word is determined on entirely phonological principles. Its key indicators include prosody (stress) and segmental phonology (vowel length). A phonological word is further produced by applying relevant phonological processes within it and not across its word boundaries. The further criterion is moraicity which requires that the minimal phonological word contains at least two moras. A grammatical word, determined entirely on grammatical principles, consists of one lexical root to which morphological processes (affixation, cliticization, and reduplication) are applied. The components of a grammatical word are cohesive and occur in a relatively fixed order. Although Murui grammatical and phonological words mostly coincide, the ‘mismatches’ include nominal compounds (that is, one phonological word consisting of two grammatical words), verbal root reduplication (one grammatical but two phonological words), and clitics.
