An analysis of Gungbe, an African language, proposes that the determiner phrase (DP) has a head-initial underlying structure, and that the determiner system involves a more articulated structure, with the DP including different functional projections. The determiner and its number projection host the specificity marker and the number marker respectively. In terms of split-determiner hypothesis, they are considered two interrelated components of the determiner and must be in local relation. Further, it is proposed that the surface noun phrase-determiner-number projection found in Gungbe and in Gbe languages generally results from application of the Generalized Licensing Criterion. Extending the split-determiner hypothesis to the Gungbe pronominal class, a tripartition is suggested, with three pronoun types identified. Contains 68 references. (MSE)
