This paper it´s about the description and analysis of relative clauses of kaingang language, which belongs to the linguistic family Ge, trunk Macro-Ge. The theoretical framework adopted to investigate the relative clauses of that language is based on authors who address their thinking under the functional perspective, such as Givón (1979), Keenan (1985), Keenan and Comrie (1997), Payne (1997) and Andrews (2007). According to these authors, the relative clause is a subordinate clause that functions as a modifier of the core of a noun phrase. The analysis and description of relative clauses aim to see how these clauses are manifested into those parameters that distinguish the relative clauses in languages . The corpus consists of data collected with indigenous informants from Apucaraninha Indigenous Land, located in the city of Tamarana-PR. The analysis indicates that the kaingang language does not present a formal relativization, in other words, with the use of any relativizing, the subordination of phrases on the main clause occurs in semantic terms. Although there are no grammatical marks in the relativized noun phrase, relative clause fulfills its role of modifier, giving communicative purposes to phrases.
