Raging beast devours men in cellar (8)
I believe the answer is:
'cellar' is the definition.
(both can mean the space underneath a house)
'raging beast devours men' is the wordplay.
'raging' is an anagram indicator.
'devours' is an insertion indicator (I've seen this in other clues).
'beast' anagrammed gives 'baset'.
'baset' enclosing 'men' is 'BASEMENT'.
'in' is the link.
(Other definitions for basement that I've seen before include "space below stairs" , "Bottom floor" , "Lower ground floor" , "Floor below ground level" , "Room at the bottom" .)
