Bound to fight? (2,3,7)
I believe the answer is:
on the warpath
'bound' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'fight?' is the wordplay.
I cannot really understand how this works, but
'fight?' could be 'war' (warring is a kind of fighting) and 'war' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for on the warpath that I've seen before include "In an angrily aggressive state" , "In a belligerent mood" , "angry" , "In a mood for battle" , "Having a hostile attitude" .)
