Be humiliated, and the rest will stop a fight (3,4)
I believe the answer is:
eat crow
'be humiliated' is the definition.
(I've seen this in another clue)
'the rest will stop a fight' is the wordplay.
I cannot quite understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
'a' is present in the answer.
'fight' could be 'row' (I've seen this in another clue) and 'row' is found in the answer.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for eat crow that I've seen before include "suffer humiliation" , "Submit oneself to humiliation" , "Humiliate oneself" .)
