This study examines the structure of relative clauses In Chaha.rnAs a quldellne , it employs the theory of Government and Binding ofrnChomsky (1981, 1982, 1986) and recent developments. The theoryrnassumes that relative clauses are Non-argument clausal complementsrnof nouns at a maximal level. The internal structure of relative clausesrnare explained interms of sublhcories and principles which are assumedrnto be prcperttes of universal grammar.rnThe study begins by analyzing the relativizing strategy in thernlanguage. It is argued that Chaha uses the Pro in situ strategy inrnIts relative clauses. This means that an empty category Pro is baserngenerated in a relativized argument NP position of a relative clause.rnThe relativized arqumcnt NP may be a complement of a verbal, a prepositionalrnor a nominal head.rnThe study shows that Chaha relative clauses are open syntacticrnpredicates predicated of their head tJPs. The head NPs act as formalrnSUbjects of their predicated relative clauses, The rule which interpretesrnthe relation between the head NPs and the predicated relativernclauses is the rule of predicate Linking which applies at S-structure.rnIn Chaha , an invariable element Iyal occurs in perfect relativernclauses to introduce the clauses as predicated of their head NPs.rnThis Iyal is treated as a complementizer and is base generated inrncornp, position at D-structure. It does not phonetically occur inrnimperfect relative clauses.rnAlthough relativized NP positions are always empty, subjectrnagreement affixes and pronominal object clltics play essential rolesrnin identifying their content. The: former refers to subjects, andrnthe latter to objects of [-N] categories.
