Consumes some cheese at supper (4)
I believe the answer is:
eats
'consumes' is the definition.
(eating is a kind of consuming)
'some cheese at supper' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'EATS' is hidden within 'cheese at supper'.
(Other definitions for eats that I've seen before include "Takes nourishment" , "worrying" , "Food (slang)" , "Comestibles" , "meal" .)
