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