Made millions inside and then got burned (8)
I believe the answer is:
cremated
'burned' is the definition.
(cremating is a kind of burning)
'made millions inside and then' is the wordplay.
I cannot quite see how this works, but
'millions' could be 'm' (abbreviation) and 'm' is found in the answer.
'made' could be 'created' ('create' can be a synonym of 'make') and 'created' is located in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'got' acts as a link.
Can you help me to learn more?
(Other definitions for cremated that I've seen before include "Of corpse, burned to ashes" , "Burnt (a body)" , "Erect dam (anag)" .)
