Patch on eye deemed somewhat flattering (7)
I believe the answer is:
honeyed
'flattering' is the definition.
(I've seen this before)
'patch on eye deemed somewhat' is the wordplay.
'somewhat' says the answer is hidden in the clue.
'HONEYED' can be found hidden inside 'patch on eye deemed'.
(Other definitions for honeyed that I've seen before include "Sweetened, made agreeable; of music pleasing to the ear" , "Sweetened (words)" , "Sweetened, flattering" , "(Of words) soothing, soft" , "Sweet" .)
