Burning match ends oddly (7)
I believe the answer is:
lighted
'burning' is the definition.
(set alight)
'match ends oddly' is the wordplay.
'match' becomes 'light' (light can mean a flame or match).
'oddly' means one should take alternating letters (letters in odd-numbered positions).
The alternating letters of 'ends' are 'ed'.
'light'+'ed'='LIGHTED'
(Other definitions for lighted that I've seen before include "Illuminated; landed" , "Given illumination" , "became cheerful" .)
