This study is motivated by assertions made by Breal (1924 [1897]) claiming that deciphering of polysemes at a synchronic level should not posit a problem because meanings of such polysemes are mainly determined by the context of the discourse: It is the context that eliminates ambiguity and foregrounds the meaning of a particular polyseme. The study is based on the tenets of relevance theory, particularly the cognitive and communicative principles, (Sperber and Wilson, 1986/1995; and Carston, 2002) to render a pragmatic account of EkeGusii polysemes. It strives to investigate how polysemous senses of EkeGusii lexical items are established and meaning deciphered. This study deduces that the meaning of a polysemous word is inferred pragmatically as a result of the addressee endeavouring to deduce what a speaker intends by the particular lexical concepts they encode; hence it is a communicative phenomenon that is highly dependent on the addressee’s ability to employ pragmatic inference.
