One who scoffs as fashionable fancy man finally takes husband's place (5)
I believe the answer is:
cynic
'one who scoffs' is the definition.
(I've seen this before)
'fashionable fancy man finally takes husband's place' is the wordplay.
I cannot quite see how this works, but
'man' could be 'cy' and 'cy' is present in the answer.
The remaining letters 'nic' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'as' is the link.
Can you help me to learn more?
(Other definitions for cynic that I've seen before include "One believing the worst" , "One critical of the motives of others" , "Person who is generally sceptical" , "One who thinks only self-interest motivates people" , "Misanthrope" .)
