Isaurian language
Isaurian is an extinct language spoken in the area of Isauria, Asia Minor. Epigraphic evidence, including funerary inscriptions, has been found into the 5th century AD. The personal names of its speakers appear to be derived from Luwian and thus Indo-European. Isaurian names containing clear Anatolian roots include Οαδας Oadas, Τροκονδας Trokondas, Κουδεις Koudeis, and Μοασις Moasis.
Isaurian personal name Τουάτρης Touatris may reflect the Indo-European root for "daughter"
