Hattic Language was spoken by the Hattians in the Anatolian peninsula prior to the rise of the Hittites. Hattic is a fascinating language that has been preserved in the Hittite corpus. It had a significant influence on both Hittite language and culture, while itself being influenced by another Anatolian language, Luwian.

This video serves as an overview, and the pictures and audio are included for visual and auditory appeal. All of the Hattic is genuine, however.
Some of the pictures are AI-generated, and I'm sure you can tell which ones.

Hattic is used as an adjective to describe the language, Hattian for everything else.
