Drinks, possibly eats (4)
I believe the answer is:
teas
'drinks' is the definition.
(tea is a kind of drink)
'possibly eats' is the wordplay.
'possibly' is an anagram indicator.
'eats' with letters rearranged gives 'TEAS'.
(Other definitions for teas that I've seen before include "Afternoon meals" , "Hot drinks" , "Beverage made by steeping leaves in water" , "Beverages from leaves" .)
