Burn with a hot liquid (5)
I believe the answer is:
scald
'burn with a hot liquid' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for scald that I've seen before include "Burn with water" , "Heat (milk) to near boiling point" , "Injure with hot liquid" , "Burn with hot liquid" , "Hurt with hot water" .)
