Sborník příspěvků věnovaných knaanštině, která byla západoslovanským jazykem, jenž používali Židé na území Polska a Čech v průběhu středověku. Canaanite glosses, i.e. medieval Slavic, especially Czech glosses, recorded in Hebrew script, have aroused the interest of researchers since the first half of the19th century. Despite long-term research their appearance has not been sufficiently described and explained until today. A conference, the contributions to which are contained in this book, was organized as a part of and supported by the grant project of the Czech Science Foundation No. P406/11/0861 Kenaanské glosy ve středověkých hebrejských rukopisech s vazbou na české země (Canaanite Glosses in Medieval Hebrew Manuscripts Related to the Czech Lands). Its goal was to diminish the number of unresolved questions by focusing on the problem of Knaanic language proper as well as connected phenomena. Many leading scholars in Hebrew, Yiddish, and Slavic linguistics have contributed to the volume. To illuminate the problem from different perspectives, scholars from related fields were welcome to contribute.
