Verb Stem Alternation in Tiv

This article investigates verb stem alternation in Tiv, a Benue-Congo language spoken primarily in Nigeria and parts of Cameroon. A descriptive analysis of alternation provides insights into the morphophonological rules governing Tiv and explains how various verb forms are derived to express grammatical categories for example tense, aspect, mood, and number. The study is framed on Halle & Marantz’s (1993) distributed morphology theory, examining the interplay encompassing syntax, morphology, and phonology in the formation of verb stems. It identifies and categorizes the various types of verb stem alternations in Tiv, including their phonological and morphological triggers. Data were elicited from native speakers and analyzed to uncover the underlying patterns and rules. Findings reveal that Tiv utilizes both morphological and morphophonological processes in its verbal system alternation, contributing to the language’s grammatical complexity. Significantly, verb stem alternation often occurring without affixation plays a central role in encoding tense, aspect, and mood. The study concludes that verb stem alternation is of significant grammatical value, reflecting the intricate structure of the Tiv verb system, which shares features with other Tivoid languages. The article recommends that verb stems in Tiv be approached alongside its tonal system, given their interrelated roles in conveying meaning.
