Char, sear (5)
I believe the answer is:
singe
This clue is a double definition.
'char' is the first definition.
(I've seen this before)
'sear' is the second definition.

(Other definitions for singe that I've seen before include "Burn; ignes (anag.)" , "superficial injury" , "Effect of fire" , "Scorch lightly" , "slight burn" .)
