indo-hittite

In Indo-European linguistics, the term Indo-Hittite (also Indo-Anatolian) refers to Sturtevant's 1926 hypothesis that the Anatolian languages may have split off the Proto-Indo-European language considerably earlier than the separation of the remaining Indo-European languages. The term is somewhat imprecise, as the prefix Indo- does not refer to the Indo-Aryan branch in particular, but is iconic for Indo-European, and the -Hittite part refers to the Anatolian language family as a whole.
