Knaanic language

Knaanic (also called Canaanic, Leshon Knaan, Judaeo-Czech, Judeo-Slavic) is a tentative name for a number of West Slavic dialects or registers formerly spoken by the Jews in the lands of the Western Slavs, notably the Czech lands, but also the lands of modern Poland, Lusatia, and other Sorbian regions. They became extinct in the Late Middle Ages. Very little is known about their difference from the surrounding Slavic languages. The largest number of samples of Knaanic written in Hebrew script are in Czech; therefore, most commonly Knaanic is associated with Old Czech.
