Settle match? (5)
I believe the answer is:
This clue is a double definition.
'settle' is the first definition.
(light can mean to settle or land)
'match?' is the second definition.
(match is a kind of light)
(Other definitions for light that I've seen before include "Airy; not heavy" , "Hint, clue" , "Undemanding; crossword answer" , "Illuminate or ignite" , "Delicate; illuminate" .)
