Eat perhaps and drink (3)
I believe the answer is:
tea
'drink' is the definition.
(tea is a drink)
'eat perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'eat' with letters rearranged gives 'TEA'.
'and' acts as a link.
(Other definitions for tea that I've seen before include "leaves much to be desired?" , "Plantation product" , "Evening meal - eat up" , "Plant" , "Assam, for instance" .)
