Drink and possibly eat (3)
I believe the answer is:
tea
'drink' is the definition.
(tea is a drink)
'possibly eat' is the wordplay.
'possibly' indicates an anagram.
'eat' anagrammed gives 'TEA'.
'and' acts as a link.
(Other definitions for tea that I've seen before include "Brew" , "Afternoon meal (3)" , "Leaves for brewing" , "Assam, for instance" , "Elevenses" .)
