Gramatyka języka polskiego Jana Otrębskiego

This paper describes a forgotten historical grammar book of Polish, which was published in the form of a multiplied typescript as a compilation of notes from the lectures delivered by Jan Otrębski at the Stefan Batory University of Vilnius in the 1930s. The notes were compiled by Otrębski’s student, Józef Trypućko. The study was published in 1933 and 1934 in two parts: one and three. Part two probably remained in the form of a manuscript. In the opinion of the authors, the study, although incomplete, provides an insight in the content of Otrębski’s lectures and the teaching of the historical grammar of Polish in Vilnius in the 1930s. It presents also the scholar’s innovative hypotheses, which cannot be found in the historical grammar books of that time.
