Involve in dispute (7)
I believe the answer is:
embroil
'involve in dispute' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for embroil that I've seen before include "Involve deeply (in a difficult situation)" , "catch up" , "Deeply involve (someone in something)" , "Incriminate" , "Involuntarily drag in" .)
