The dictionary «Classics of Russian Literature in the Mirror of Winged Expressions» (experience of the dictionary-reference book) aims to attract both the broad Russian reader, schoolchildren and students to a more conscious and profound study of Russian classical literature. The incentive for this, according to our concept, can be linguistic units that are explicitly or implicitly known to many native speakers of the Russian language and are widely used in modern literature, the press, television programs and the Internet. Winged words and expressions are linguistic clusters of knowledge of classical literature and culture. Selection of such units in the dictionary will be carried out using the methodology of a linguistic experiment - a sociolinguistic survey of informants from different cities of Russia. Created on the scientific philological basis and the principles of the Larin lexicography, the projected dictionary can be widely used as a reference tool for improving the culture of speech and deepening knowledge about the Russian classics.
