The principal known member of the Anatolian division of the Indo-European family is Hittite, the tongue of the Hittites, who entered and conquered much of Anatolia early in the 2d millennium b.c. The oldest surviving written records of Hittite, dated at about the 15th or 14th cent. b.c., are among the earliest extant remains of any Indo-European language. From c.1500 to 1200 b.c., Hittite was written both in cuneiform (a system of writing taken over from Mesopotamia) and in hieroglyphics (a form of picture writing unrelated to the hieroglyphics of Egypt). After the fall of the Hittite Empire (c.1200 b.c.) the use of cuneiform ceased, but writing in hieroglyphics continued until the 7th cent. b.c. Cuneiform and Hieroglyphic Hittite are separate but closely related languages.

A near relative of Hittite was Luwian, the Anatolian language of the now extinct Luwian people. Dominant in a large part of S Anatolia during the period of the Hittite Empire, Luwian was written in cuneiform, and its surviving documents go back to the 14th cent. b.c. In areas of N Anatolia, Palaic flourished. Also close to Hittite, it was written in cuneiform. Grammatical features common to Hittite, Luwian, and Palaic include: two genders, one of which combines masculine and feminine as a common gender and the other of which is neuter; two moods, indicative and imperative, the first of which has a present and a preterit tense; and two voices, active and middle. Lycian, a language of SW Anatolia for which there are written records dated from about the 5th to 4th cent. b.c., may have been a continuation of Luwian. Lycian was written in a form of the Greek alphabet, as was Lydian. Lydian was spoken in W Anatolia, and the surviving written records date from about the 5th to 4th cent. b.c.
