He won’t yield, but he does go in a bit (5)
I believe the answer is:
bigot
'he won't yield but he' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'go in a bit' is the wordplay.
'in' means one lot of letters goes inside another.
'go' put within 'bit' is 'BIGOT'.
'does' acts as a link.
Can you help me to learn more?
(Other definitions for bigot that I've seen before include "Intolerant type" , "Racist or sexist?" , "Intolerantly prejudiced person" , "Dogmatist" , "One is prejudiced and intolerant" .)
