Proto-Hittite is the name given by Dr. Forrer to the prefixal language, examples of which are found in the cuneiform texts of Boghaz Keui. In them it is called Khattilis “Hittite”, the mixed official language of Boghaz Keui being known as “the language of the scribes” (EME sa ameli dubbi, Annals of Archœology, iii, 3, pl. xxvi, 1, 12). This latter was, in fact, a mixture of Sumerian, Assyrian, and Indo-European elements on the basis of an Asianic language which was spoken in Arzawa (Western Cilicia) and Kizzuwadna (of which the southern Qumani or Komana was the capital). The royal line of Boghaz Keui, as their names show, originally spoke Proto-Hittite, and must have given the name of Khattu and Khattusis (“Silver-town”) to the city which they made their capital after the conquest of the surrounding territory. They came from Kussar, written Kursaura in earlier documents, the Garsaura of classical geography, and their capital had been Arinna (“Well-town”), the Phreata of Ptolemy. Here their annals reached back to the time when Sargon of Akkad had invaded their country (2800 b.c.).
