The grammaticalization path of the Kaakye relative clause marker

Languages develop their relative markers from a variety of sources. This paper examines the paths along which the relative marker in Kaakye, (a Kwa Niger-Congo language) has developed. Using the concept of grammaticalization as a framework, evidence suggests that the Kaakye relative marker kɛ́ originates from the manner demonstrative adverb kɛ́nɩ̀ŋ̀ , which means ‘in such a manner’ or ‘like this/that.’ The grammaticalization process begins with desemanticization, where the adverb’s concrete meaning, tied to its deictic reference, is first used to specify a referent noun phrase. Over time, this function evolves into a more abstract grammatical element, ultimately developing into a relative marker. Other mechanisms of grammaticalization such as extension, decategorialization and erosion, and Hopper’s principles of divergence associated with development process are discussed. Though the relativizer is derived from a demonstrative as it is attested in other languages, the particular grammaticalization path identified is quite unique. The paper contributes to the study of grammaticalization in general and provides a particular piece of evidence to support demonstratives as sources of relative markers.
