Ancient land in Asia Minor (5)
I believe the answer is:
ionia
'ancient land in asia minor' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ionia that I've seen before include "Aegean region which gives its name to the adjacent sea" , "East coast of the Aegean in Classical times" , "Ancient area" , "Ancient Greek colony" , "Ancient Greek region" .)
