The contribution shows high importance of early Czech-Jewish linguistic contacts for Czech studies. It (1) briefly mentions the role of Hebrew in medieval linguistic thought with respect to the Czech lands, (2) summarizes the contacts preceding the 14th century, (3) elaborates on the problem of the oldest Czech sentence, (4) brings new information about Roman Jakobson’s work in the field including so far unpublished materials from his papers stored at MIT in Cambridge, MA, (5) corrects some misleading results of previous research, (6) treats the question of the Czech layer in Yiddish, (7) supplies some examples of linguistic importance of medieval Czech glosses in Hebrew script, and (8) enumerates goals of future research.
