Hittite

Language used by the Hittites, an ancient people that lived in Anatolia in modern Turkey.
The name the Hittites used for their language was nesili, "language of Nesa." Nesa being one of the Anatolian cities.
Hittite language was introduced to Anatolia and northern Syria in the beginning of the 19th century BCE. Hittite language was an Indo-European language, but was soon exposed to influences from local languages. Elements from Proto-Indo-European languages did survive for centuries, however.
The most important changes to the language came with lexical and phonetic changes. Vowels and new terms were borrowed from local languages.
Numerous books and tablets in the Hittite language have been preserved. The sources to Hittite language occur in 2 variations, cuneiform and hieroglyphic. Cuneiform provides the oldest, dating back to 1600 BCE. These texts represent the oldest written examples of any Indo-European language. There are no sources for Hittite that are more recent than 3000 years.

Hittite is the extinct language once spoken by the Hittites, a people who once created an empire centered on ancient Hattusas in north-central Anatolia. The language was spoken from approximately 1600 BC to 1100 BC. There is some attestation that Hittite and related languages continued to be spoken in Anatolia for a few hundred years following the collapse of the Hittite empire and the last of the Hittite texts.
