This paper considers some cases of interference on the basis of form and semantics, as in Russian words ultimately related to Proto-Slavic verbs *mesti, *męsti and *męti. The interference is shown to have started as early as in the Proto-Slavic period. Also, several conclusions are drawn regarding the direction and conditions of these instances of interference in word families in the history of the Russian language, necessitating some amendments to the existing etymological versions of specific words.
