The aim of this paper is to identify and describe the means of expressing concessive relations in the Yakut language. It is established that concessive constructions are first of all represented by nuclear means, namely, analytical-synthetical polypredicative constructions with dependent predicates followed by postpositions as well as by conditional mood combined with analytical markers. The peripheral means of expressing the relations under discussion include analytical constructions with postpositional or prepositional conjunctions. Thereby analytical polypredicative constructions describe not only concessive but also concessive-adversative relations and adversative relations proper. In the domain of polypredicative constructions which express the relations under discussion there are functionally synonymous constructions. This is conditioned by the fact that many prepositional conjunctions are structural variants of analytical-synthetical and analytical (postpositional) connecting means.
