The relative verb forms of Cuwabo (Bantu P34) as contextually oriented participles

Abstract Cuwabo (Bantu P34, Mozambique) illustrates a relativization strategy, also attested in some North-Western and Central Bantu languages, whose most salient characteristics are that: (a) the initial agreement slot of the verb form does not express agreement with the subject (as in independent clauses), but agreement with the head noun; (b) the initial agreement slot of the verb form does not express agreement in person and number-gender (or class), but only in number-gender; (c) when a noun phrase other than the subject is relativized, the noun phrase encoded as the subject in the corresponding independent clause occurs in post-verbal position and does not control any agreement mechanism. In this article, we show that, in spite of the similarity between the relative verb forms of Cuwabo and the corresponding independent verb forms, and the impossibility of isolating a morphological element analyzable as a participial formative, the relative verb forms of Cuwabo are participles, with the following two particularities: they exhibit full contextual orientation, and they assign a specific grammatical role to the initial subject, whose encoding in relative clauses coincides neither with that of subjects of independent verb forms, nor with that of adnominal possessors.
