The Russian lexicon is enriched primarily through word formation. Most Russian words are derived from other words, and the rich word-formation possibilities of Russian allow for the derivation of words according to certain models. As a result of word-formation processes, there are “nests” (gnezda) of words, occasionally dozens of them, that share a common root, for example: letet’ – vletet’, zaletet’, pereletet’, priletet’, uletet’, letat’, vletat’, lyotchik, polyot, etc. Prefixes and suffixes add nuances of meaning and emotional coloring. Knowledge of word formation helps with the comprehension of Russian texts, where authors frequently use neologisms that do not appear in dictionaries, and the ability to deploy word-formation techniques increases one’s vocabulary and significantly enriches speech
