Burn for a wicked deed on empty grave (5)
I believe the answer is:
singe
'burn' is the definition.
(singing is a kind of burning)
'a wicked deed on empty grave' is the wordplay.
'a wicked deed' becomes 'sin' (I've seen this before).
'on' is a charade indicator (letters next to each other).
'empty' suggests removing the centre.
'grave' with its centre taken out is 'ge'.
'sin'+'ge'='SINGE'
'for' acts as a link.
(Other definitions for singe that I've seen before include "Earnest entreaty" , "Superficial burn" , "Burn slightly on surface" , "Char, burn slightly" , "Char, scorch" .)
