Entangle or involve (7)
I believe the answer is:
embroil
I believe this is a double definition.
'entangle' is the first definition.
(I've seen this before)
'involve' is the second definition.
(I know that embroil is a more specific form of involve)
(Other definitions for embroil that I've seen before include "Involve (someone) in a dispute" , "In difficulties, involve" , "Drag in - bole rim (anag)" , "catch up" , "Involuntarily drag in" .)
