Streszczenie:
The influences of Czech are evident in medieval and later Christian terminology as well as religious and Biblical Sorbian writings up to the 19th century. From the 1840s onward, Czech intensely affected the lexical system and style variations of literaiy Upper Sorbian. The Pful dictionary (1866) and 19th century Upper Sorbian writings (mainly the press) document over one thousand lexical units derived from Czech, only some of which found either a permanent or temporary place in Upper Sorbian. Bohemisms are much less frequent in Lower Sorbian, the penetration occurring mostly via Upper Sorbian.
