Suit and tie (5)
I believe the answer is:
match
I believe this is a double definition.
'suit' is the first definition.
(I've seen this before)
'tie' is the second definition.
(thesaurus)
'and' is the link.
(Other definitions for match that I've seen before include "Lighter; contest" , "Go together" , "Contest; pair" , "Fixture - fit with - smoker's aid" , "tie" .)
