Chicken wearing beret? (5)
I believe the answer is:
capon
'chicken' is the definition.
(I know that capon is a type of chicken)
'wearing beret?' is the wordplay.
I cannot really understand how this works, but
'beret?' could be 'cap' (beret is a type of cap) and 'cap' is present in the answer.
The remaining letters 'on' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for capon that I've seen before include "Castrated cock fowl" , "for lunch, perhaps" , "Castrated cock fattened for eating" , "fowl fattened for pot" , "Bird fattened for eating" .)
