Discuss terms (9)
I believe the answer is:
negotiate
'discuss terms' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for negotiate that I've seen before include "Find a way over (a difficult path)" , "as diplomat does" , "Discuss the terms of an arrangement" , "Try to reach agreement through discussion" , "Bring about by mutual agreement" .)
