This monograph conducts a syntactic study of Tuki, a Bantu language spoken in Cameroon, from a cartographic perspective. The following domains are meticulously explored: The Complementizer Domain, the Inflectional Domain and the Verbal Domain. This study reveals that there is a relative phrase (RelP) located between ForceP and FocP. Moreover, a detailed analysis of an articulated IP provides the order of clausal functional heads that manifest aspectual morphology, which is theoretically closely related to issues in adverbial syntax. Additionally, the language under study unveils a very rich structural make up of DP and the surface word orders attested in this phrase can be accounted for in terms of snowballing movement operations along the lines previously sketched in the format of the Split DP Hypothesis. Overall, this cartographic analysis is bound to enrich our morphosyntactic knowledge of UG clausal architecture by demonstrating that its rich underlying structural skeleton is correlated by a wealthy surface structural and functional map.
