The article discusses the role of verb-building prefixes in Tajik and English. Based on the materials of the dictionaries of P. Jamshedov and T. Razi, as well as A. Mamadnazarov, the features of the formation of derivative verbs in both languages are considered. On the example of Tajik prefix боз- and English re- the cases of combining both word-building elements with words are shown, the range of meanings of such derivatives verbs that have a limited and extensive possibility is revealed and the derivative verbs in Tajik and English express from one to nine meanings. It is concluded that the possibilities of connecting such prefixes in English are wider compared to Tajik, and they are attached not only to verbs, but also to nouns, deriving new words which express actions and situations.
