Suit with tie (5)
I believe the answer is:
match
I believe this is a double definition.
'suit' is the first definition.
(both can mean to go together)
'tie' is the second definition.
(I've seen this before)
'with' acts as a link.
(Other definitions for match that I've seen before include "Partnership" , "You can have a love or shouting one" , "Striker < in suit" , "Go together" , "tie" .)
