Lighter suit (5)
I believe the answer is:
match
I believe this is a double definition.
'lighter' is the first definition.
(match is a kind of lighter)
'suit' is the second definition.
(I've seen this before)
(Other definitions for match that I've seen before include "one's struck" , "tie" , "Equal - lucifer" , "Contest; correspond" , "Marriage; game" .)
