Fight that won't stop you talking to someone (3,2,5)
I believe the answer is:
war of words
'won't stop you talking to someone' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'fight' is the wordplay.
I cannot quite understand how this works, but
'fight' could be 'war' (warring is a kind of fighting) and 'war' is present in the answer.
This may be the basis of clue (or it may be nonsense).
'that' acts as a link.
Can you help me to learn more?
(Other definitions for war of words that I've seen before include "Slanging match" , "Bitter argument" .)
