The ancient Cappadocian language was an ancient language or group of languages spoken in Asia Minor, possibly related to Hittite or Luwian.
[2][3] If Luwian, it may have been related to the dialect of Tabal.
[3] However, there are no known texts in this language.
[4] Strabo and Basil of Caesarea state that it was not Greek.
[2][5] It was ultimately replaced by Koine Greek, but appears to have survived in some locations until at least the 6th century CE.
