In his paper, the author examines a possible implementation of the lexeme 'predat' ' endowed with the meaning 'hand over' into the Slovak lexical inventory. Leaning on instances of this lexeme in Slovak historical sources and with regard to its development in other Slavonic languages, the author comes to the conclusion that the said meaning must be considered as new and out-of-system in the Slovak language. Investigation into existence of this phenomenon in other Slavonic languages as well as into the meanings of the lexeme in Old Slavonic shows that the Slovenian, Polish, Upper and Lower Lusitian languages exhibit more or less the same situation, while the South and East Slavonic languages along with Czech make up a separate isogloss characterized in its development by the prefixes 'pro-, pre-, or pere-'.
