High Quality Content by WIKIPEDIA articles! Luwian (sometimes spelled Luvian), rarely Luish, is an ancient language or languages of the Anatolian branch of the Indo-European language family. The two varieties of Luwian are named for the different scripts they were written in: Cuneiform Luwian, or CLuwian, and Hieroglyphic Luwian, or HLuwian. As to whether these were one language or two, there is no consensus. They may have constituted a dialect continuum.
