Have for tea, perhaps? (3)
I believe the answer is:
eat
'have' is the definition.
(eating is a kind of having)
'tea perhaps?' is the wordplay.
'perhaps?' indicates an anagram (I've seen 'perhaps' mean this).
'tea' anagrammed gives 'EAT'.
'for' acts as a link.
(Other definitions for eat that I've seen before include "and 27: Be humiliated" , "Scoff" , "Have 23d [MEAL]" , "Be corrosive" , "Gobble up" .)
