The Luwian language is an ancient Anatolian language that was spoken in what is now modern-day Turkey. It belongs to the Hittite branch of the Indo-European language family and was used primarily during the second millennium BCE. Luwian is known from inscriptions and texts, often written in hieroglyphic or cuneiform scripts. Luwian was used by various cultures, including the Hittites and the Luwians, who inhabited regions in western and southern Anatolia. The language played a significant role in the political and cultural exchanges of the time, influencing neighboring languages and cultures in the ancient Near East.
