Consumes some cheese at suppertime (4)
I believe the answer is:
eats
'consumes' is the definition.
(eating is a kind of consuming)
'some cheese at suppertime' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'EATS' is hidden in the letters of 'cheese at suppertime'.
(Other definitions for eats that I've seen before include "Devours - food" , "Swallows food" , "Commonly, they eliminate" , "Provisions" , "Food (colloq.)" .)
