It burns one's palm, possibly (4)
I believe the answer is:
lamp
'it burns one's' is the definition.
The definition suggests a singular noun which matches the answer.
'palm possibly' is the wordplay.
'possibly' indicates anagramming the letters.
'palm' anagrammed gives 'LAMP'.
Can you help me to learn more?
(Other definitions for lamp that I've seen before include "This could be standard" , "punch" , "Device for giving light on palm" , "Florence Nightingale was the Lady with the . . . ." , "Source of light, usually portable" .)
