ヒッタイト語
Hittite cuneiform is an adaptation of the Old Assyrian cuneiform of c. 1800 BC to the Hittite language. When the cuneiform script was adapted to writing Hittite, a layer of Akkadian logographic spellings was added to the script, thus the pronunciations of many Hittite words which were conventionally written by logograms are now unknown.
