Dokładna nauka języka i stylu polskiego w dwoch częściach. Cz. 1 Tomasza Szumskiego

Tomasz Szumski (1778–1840) was a polyglot, teacher, bookseller, author of school textbooks, associated with Greater Poland. His grammar book, released in 1809, is the first Polish-language grammar book of the Polish language published in the 19th century where the grammatical description of Polish is made independent of the description of Latin. It is at the same time the first known 19th-century grammar of Polish where the author dared to polemicise with Onufry Kopczyński’s ideas contained in the Polish–Latin Grammatyka dla szkół narodowych (Grammar for national schools).
