The article covers the actualization of quasi antonymous relations in the lexical system of Russian national dialects. The phenomenon of quasi antonymy can be observed both in dialects and the colloquial speech. Taking into consideration the process of its functioning, we can say that quasi antonymy acts in the quasi antonymous oppositional form. When compared to the accurate (“true”) antonymous oppositions, quasi antonymous oppositional structure has a higher degree of semantic asymmetry and the part of speech heterogeneity, but less regular joint repeatability. In the article there are described some types of quasi antonymous oppositions in dialects, taking into account the character of linguistic units as well as the relations between their parts.
