“As a material of literature, the Slavic-Russian language has an undeniable superiority before all European ones: his fate was extremely happy. In the XI century, the ancient Greek language suddenly discovered his vocabulary, the treasury of harmony, granted him the laws of his thoughtful grammar, his excellent turnover, a magnificent course of speech; In a word, he adopted it, thus eliminating it from slow improvements in time. By itself, it is already sonorous and expressive, he has borrowed flexibility and correctness. The common adverb had to be separated from the book; But subsequently they became close, and such is the element given to us for the message of our thoughts. ” A.S. Pushkin
