Has some wine at supper (4)
I believe the answer is:
eats
'has' is the definition.
(eating is a kind of having)
'some wine at supper' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'EATS' is hidden within 'wine at supper'.
(Other definitions for eats that I've seen before include "meal" , "Seat (anag.)" , "Ingests" , "Takes nourishment" , "worrying" .)
