Karaim
The Karaim language (Crimean dialect: къарай тили, Trakai dialect: karaj tili, traditional Hebrew name lashon kedar, לשון קדר‎, "language of the nomads") is a Turkic language with Hebrew influences, in a similar manner to Yiddish or Judaeo-Spanish. It is spoken by only a few dozen Crimean Karaites (Qrimqaraylar) in Lithuania, Poland and Crimea and Galicia in Ukraine. The three main dialects are those of Crimea, Trakai-Vilnius and Lutsk-Halych all of which are critically endangered. The Lithuanian dialect of Karaim is spoken mainly in the town of Trakai (also known as Troki) by a small community living there since the 14th century. There is a chance the language will survive in Trakai as a result of official support and because of its appeal to tourists coming to the Trakai Island Castle, where Crimean Karaites are presented as the castle's ancient defenders.
