The aim of the article is to elucidate the polysemy of Slovak modal verbs from the point of view of G. Lakoff 's prototypes. The process of grammaticalization has shown that high polysemy is the common denominator of basic modal verbs in Slavic languages. Moreover, it has helped to uncover the primary/original grammatical function of the full meaning verb have with a specific lexical meaning of possession.
