O wyjątkowym średniowiecznym komentarzu do tłumaczenia modlitw

The paper is an analysis of a mediaeval grammatical commentary on translation of prayers into Polish (from the manuscript BJ 1297). The author discusses the various problems that the writer engages in the context of the preserved copies of basic prayers. The paper reveals the unusual linguistic awareness of the writer who uses the grammatical system of Latin, with which he is acquainted, to build a mode of thinking about Polish, and who reflects upon Polish, recognizes its diversification, and sees in it a chance to express the content enclosed in Latin structures. The commentary is simultaneously metatextual and metalinguistic as the writer uses, through the discussed texts, the grammar of contemporary Polish as his subject of reference.
