The object of the analysis presented in this paper is five pairs of structures, composed of a correct synthetic structure and a corresponding analytic structure, which is disapproved of in terms of prescriptivism yet occurring quite frequently in utterances by contemporary language users. Due to subtle semantic differences between the synthetic and analytic forms, the latter one is beginning to win the speakers’ approval and is slowly being absorbed by the language system. The process is evidence of the intensifying tendency for analysation of the Polish language, which was observed already in the 16th-century texts and is a source of the increasing number of syntactic synonyms today.
