Marriage with a redhead? (5)
I believe the answer is:
match
'marriage' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for match that I've seen before include "one's struck" , "Sporting event" , "An exact duplicate or a contest between two" , "Marriage; game" , "Correspondence" .)
