Indian city ruddy uplifting, setter maintains (6)
I believe the answer is:
mysore
'indian city' is the definition.
(I've seen this before)
'ruddy uplifting setter maintains' is the wordplay.
'ruddy' becomes 'rosy' (I can't justify this - if you can you should give a lot more credence to this answer).
'uplifting' shows that the letters should be reversed in order.
'setter' becomes 'me' (the setter of the clue).
'maintains' is an insertion indicator.
'rosy' written backwards gives 'ysor'.
'ysor' put inside 'me' is 'MYSORE'.
Can you help me to learn more?
(Other definitions for mysore that I've seen before include "Indian city?" , "city of India" .)
