Save somebody from going bad? (6)
I believe the answer is:
embalm
'save' is the definition.
(embalming is a kind of saving)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for embalm that I've seen before include "Preserve from decay in death with chemicals" , "Preserve body, mummify" , "Treat corpse with preservatives" , "Use chemicals to preserve a dead body from decay" , "Make into mummy" .)
