Pushkin is usually credited with developing Russian literature. He is seen as having originated the highly nuanced level of language which characterizes Russian literature after him, and he is also credited with substantially augmenting the Russian lexicon. Whenever he found gaps in the Russian vocabulary, he devised calques. His rich vocabulary and highly-sensitive style are the foundation for modem Russian literature. His accomplishments set new records for development of the Russian language and culture. He became the father of Russian literature in the 19th century, marking the highest achievements of the 18th century and the beginning of literary process of the 19th century. He introduced Russia to all the European literary genres as well as a great number of West European writers. He brought natural speech and foreign influences to create modem poetic Russian. Though his life was brief, he left examples of nearly every literary genre of his day: lyric poetry, narrative poetry, the novel, the short story, the drama, the critical essay and even the personal letter.
