Między gramatyką opisową a normatywną. Jeszcze o Józefie Mrozińskim.

Between descriptive and prescriptive grammar. Once again about Józef Mroziński Summary Józef Mroziński is a well-known fi gure in linguistics. He is normally perceived as the fi rst modern Polish grammarian–descriptivist, who endeavoured to formulate the rules governing the Polish language. His achievements have been an object of numerous studies and one could have the impression that everything has already been written about them. Yet, it is worth examining them once again as, apart from theoretical assumptions and description of the language, his studies present also prescriptive assumptions, which had not been applied until the 20th century. The aim of this paper is to reconstruct the assumptions.
