Box me up inside and dispose of the body (7)
I believe the answer is:
cremate
'dispose of the body' is the definition.
I can't judge whether this defines the answer.
'box me up inside' is the wordplay.
'box' becomes 'crate' (crate is a kind of box).
'up' indicates anagramming the letters (letters get chucked up).
'inside' indicates putting letters inside.
'me' anagrammed gives 'em'.
'crate' enclosing 'em' is 'CREMATE'.
'and' is the link.
Can you help me to learn more?
(Other definitions for cremate that I've seen before include "Burn a body to ashes" , "Burn a corpse to ashes" , "set alight" , "Have a burn-up" , "Burn (a dead body)" .)
