Idiomatic Expressions can enrich the speech and make the speech becomes more interesting. The ability to apply the idiomatic expressions shows that the person has an advance level of the language comprehension and fluency. This happens since the structures and the meanings of the idiomatic expressions do not follow the conventional patterns of the language. Metaphors connected to culture are very thick in idioms. For this reasons, the teachers and the students need to examine more deeply the morphosyntax and the semantics to make sure the precision in the interpretations of idioms. This paper discusses the idioms in Russian language, more specifically connected to the names of animals connected to the myth and legend of Russian and Slavic using the morphosyntax and the semantics. In the results, the Russian culture will be revealed through the idioms. The source for the idioms is the book titled “A book of Russian Idioms ilustrated” written by MI Dubrovin and ilustrated by VI Tillman (1980).
