Luwian language
Luwian (; sometimes spelled Luvian, rarely Luish) is an ancient language or group of languages of the Anatolian branch of the Indo-European language family. The two varieties of Luwian are named for the scripts that they were written in: Cuneiform Luwian (CLuwian) and Hieroglyphic Luwian (HLuwian). As to whether these were one language or two, there is no consensus.
Several other languages in Anatolia have been identified as being most similar to Luwian, which suggests that they belong in their own branch with CLuwian and HLuwian. Some linguists name the branch "the Luwian Group" or just "Luwian" and, in that sense, Luwian means all of the Luwian languages. Other linguists, following Melchert, prefer to use Luwic for the branch and Luwian for CLuwian and HLuwian. Proto-Luwian can mean the common ancestor of the two, or the common ancestor of the several although, in the tree-naming conventions, if the branch is to be called Luwic, its ancestor should be Proto-Luwic or Common Luwic.
