Luwian language
The Luwian language is attested in two different scripts, cuneiform and Anatolian hieroglyphs, over more than a millennium. While the earlier scholarship tended to treat these two corpora as separate linguistic entities, the current tendency is to separate genuine dialectal distinctions within Luwian from orthographic differences. Accordingly, one now frequently speaks of Kizzuwatna Luwian (attested in cuneiform transmission), Empire Luwian (cuneiform and hieroglyphic transmission), and Iron Age Luwian / Late Luwian (hieroglyphic transmission), as well as several more Luwian dialects, which are more scarcely attested.
