Judah ibn Kuraish Judah ibn Kuraish (Hebrew: יהודה אבן קריש‎ ‎ , Arabic: يهوذا بن قريش‎ ‎ ), was a North African Jewish grammarian and lexicographer. He was born at Tiaret in North Africa and flourished in the 9th century. While his grammatical works advanced little beyond his predecessors, he was the first in studying comparative philology in Hebrew, Aramaic and Arabic. He recognized that the various Semitic languages are derived from one source and that although they are different in their development, they are subject to the same linguistic laws. Judah's grammatical researches were original, and he maintained his views regardless of the "Mishnah" and the "Talmud" so he has been erroneously considered a Karaite.
