What is the meaning of Hittite?

(n.) A member of an ancient people (or perhaps group of peoples) whose settlements extended from Armenia westward into Asia Minor and southward into Palestine. They are known to have been met along the Orontes as early as 1500 b. c., and were often at war with the Egyptians and Assyrians. Especially in the north they developed a considerable civilization, of which numerous monuments and inscriptions are extant. Authorities are not agreed as to their race. While several attempts have been made to decipher the Hittite characters, little progress has yet been made.
