Region of ancient Turkey (5)
I believe the answer is:
ionia
'region of ancient turkey' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ionia that I've seen before include "Old region in Asia Minor" , "Greek area of Asia Minor" , "East coast of the Aegean in Classical times" , "ancient region of Eastern Mediterranean" , "Ancient region of Asia Minor" .)
