Talk with the other side (8)
I believe the answer is:
I believe this clue is a double definition.
'talk' is the first definition.
(I know that converse is a more specific form of the action talk)
'other side' is the second definition.
'with the' is the link.
(Other definitions for converse that I've seen before include "Quite the opposite!" , "express thoughts and ideas?" , "Communicate with" , "take part in discussion" , "Have a chat, being contrary" .)
