Important Indian seen as unharmonious on reflection (4)
I believe the answer is:
raja
'important indian' is the definition.
(I've seen this in another clue)
'unharmonious on reflection' is the wordplay.
'unharmonious' becomes 'ajar' (I've seen this in another clue).
'on reflection' is a reversal indicator.
'ajar' backwards is 'RAJA'.
'seen as' acts as a link.
(Other definitions for raja that I've seen before include "Eastern leader" , "High Indian position" , "sovereign" , "Prominent Indian" , "Indian prince or king" .)
