This article aims to describe the functioning of non-verbal predicates in Akwá, a Bantu language of the C20 group of M. Guthrie, drawing inspiration, on a theoretical level, from the principles of Martinetian functionalism. Thus, by the mechanism of juxtaposition which makes it possible to form bimonematic utterances, the non-verbal predicates are assumed by the monemes belonging mainly to the classes of nominals, pronouns, adjectives and many other grammatical categories. However, in monomonematic utterances, the non-verbal predicative function is assumed, apart from nominals, by adverbs and interjections whose different uses serve to formulate insults, slogans or greetings.
