This thesis deals with description of the structure of relative clause in Bòrná. Concerning thernways of relativization of Bòrná, there is a controversy as to whether the relative pronoun is used orrnnot. According to Lamberti (1993), elements like /tsó, tsú, tsúwoótsÃ, iruwó, iruú, iruwoótsÃ, ettuwó,rnettuú, ettuwoótsÃ/ are relative pronouns in Bòrná and implies relative pronoun strategy.rnWhereas, Bikila (2003) and Felming (1976) maintained that /-ts/ is a relativizer.rnBut the position of the present study is like Bikila (2003) and Felming (1976) claim /ts/ is arnrelativizer, the element is portmantu that encodes relativity of the verb and past tense. Thernlanguage employs pro in situ, pronoun retention and gapping strategy. The pro in situ strategyrnoccurs in postnominal subject and direct object relativization. The prenominal subject and directrnobject relativization employs gapping strategy. The rest of the positions like indirect object,rnoblique complement and possessor position apply pronoun retention strategy. Based on thernposition of the RC with respect to head noun, Bòrná RC has a prenominal, postnominal andrnheadless type of relative clause. Bòrná has no restrictiveness marker of structure of relativerncluase. That is, the meaning of the relative cluase is not restricted or non-restricted by eitherrnformal or distributional change. In connection to these, Keenan and Comrie (1977)’s fivernaccessibility hierarchy: subject, direct object, indirect object, oblique complement and possessorrnposition relativizations Bòrná covers all the accessibility hierarchy positions.rnThe function of adjectives and the RC is similar in Bòrná; both can function as headless,rnprenominal and postnominal. In the language, negative relative verb drops tense marker and addrnnegative suffix /-á/. /-á/ is a portmantu morpheme that negates verbs in present, past and futurerntenses and encodes relativity of the verb.
