Fat, curvy character in the capacity of a bishop (5)
I believe the answer is:
squab
'fat' is the definition.
(I've seen this before)
'curvy character in the capacity of a bishop' is the wordplay.
'curvy character' becomes 's' (I am not sure about the 'curvy' bit.).
'in the capacity of' becomes 'qua' (I've seen this in another clue).
'a bishop' becomes 'B' (chess abbreviation).
's'+'qua'+'b'='SQUAB'
Can you help me to learn more?
(Other definitions for squab that I've seen before include "Young pigeon" , "Fledgling" , "young bird" , "Thick cushion" , "Little bird" .)
