Asian region in Chennai? No, Islamabad, on reflection (5)
I believe the answer is:
ionia
'asian region' is the definition.
'Ionia' can be an answer for 'region' (Ionia is an example). I am unsure of the 'asian' bit.
'in chennai? no islamabad on reflection' is the wordplay.
'in' says the answer is hidden in the clue.
'on reflection' shows that the letters should be reversed in order.
'ainoi' is hidden within 'chennai no islamabad'.
'ainoi' written backwards gives 'IONIA'.
Can you help me to learn more?
(Other definitions for ionia that I've seen before include "Greek area of Asia Minor" , "Ancient Greek colony" , "Aegean region which gives its name to the adjacent sea" , "Ancient Greek region" , "ancient region of Eastern Mediterranean" .)
