Hittite (Hebrew: חִתִּית) is the extinct language once spoken by the Hittites, a people who created an empire centered in Hattusa in north-central Anatolia.
Hittite is the oldest recorded Indo-European language, but it had remained completely unknown during the period in which Indo-European linguistics developed, because its records are on clay tablets that were excavated only at the end of the 19th century.
Akkadian is an extinct Semitic language that was spoken in ancient Mesopotamia. This was the language of the Epic of Gilgamesh and other stories that influenced some of the stories in the Old Testament.
Aramaic is a Semitic language that belongs to Northwest Semitic group of languages, which also includes Canaanite languages such as Hebrew and Phoenician. Aramaic script was widely adopted for other languages like Arabic and Hebrew alphabets. There is no one singular Aramaic language, but each time and place has had its own variation.
