Taken for tea, perhaps (3)
I believe the answer is:
ate
'taken' is the definition.
(eating is a kind of taking)
'tea perhaps' is the wordplay.
'perhaps' indicates an anagram.
'tea' anagrammed gives 'ATE'.
'for' is the link.
(Other definitions for ate that I've seen before include "included in one's diet" , "Greek goddess of mischief" , "Had at meal" , "Devoured" , "Ingested" .)
