Turkish is a relative newcomer to Anatolia. Before the Turks arrived, there were Lydians, Lycians, Hittites, Luwians, etc and they spoke languages within the Indoeuropean subgroup called Anatolic Languages. Not closely related to modern Turkish at all.
As young people would say, “no, duh!” And in between the times you point to and the Turkish conquest, most folks in Asia Minor spoke Greek, another Indo-European Language.
Why folks feel like posting things which are actually amplifications of the point I made as if they were correcting me, I really don’t know. As I pointed out, the title is stupid in the context of an article on linguistics and based on nothing other than kowtowing to the conceit of Ataturk and his political heirs that anything on the territory of the present Republic of Turkey is “Turkish”.
