Put a match to and left it (3)
I believe the answer is:
lit
'put a match to' is the definition.
(I've seen this in another clue)
'left it' is the wordplay.
'left' becomes 'L' (common abbreviation).
'l'+'it'='LIT'
'and' is the link.
(Other definitions for lit that I've seen before include "Set alight" , "Set fire to" , "Set afire" , "Fired" , "Burning" .)
