Joins battle with marriage in mind? (7)
I believe the answer is:
engages
'joins' is the definition.
The answer and definition can be both to do with contact as well as being verbs in their -s form.
Perhaps you can see an association between them that I can't see?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for engages that I've seen before include "books" , "Employs, hires" .)
