For whom fancy nicety is too much? (5)
I believe the answer is:
cynic
'for' is the definition.
Both the answer and definition are singular nouns.
Perhaps you can see an association between them that I don't see?
'whom fancy nicety is too much?' is the wordplay.
'is too much?' indicates the answer is hidden within the clue (only some letters needed - the rest are 'too much').
'CYNIC' is hidden within 'whom fancy nicety'.
Can you help me to learn more?
(Other definitions for cynic that I've seen before include "One with a low view of human nature" , "Person who is generally sceptical" , "Pessimistic viewer of human motives" , "one with little faith in human nature" , "Doubter of others' motives" .)
