ルウィ語
While almost all the preserved texts employing Anatolian hieroglyphs are written in the Luwian language, some features of the script suggest its earliest development within a bilingual Hittite-Luwian environment. For example, the sign which has the form of a "taking" or "grasping" hand has the value /ta/, which is precisely the Hittite word ta-/da- "to take," in contrast with the Luwian cognate of the same meaning which is la-. There was occasionally some use of Anatolian hieroglyphs to write foreign material like Hurrian theonyms, or glosses in Urartian (such as "á - ḫá+ra - ku" for "aqarqi" or "tu - ru - za" for "ṭerusi", two units of measurement).
