Dine in tea-break (3)
I believe the answer is:
eat
'dine' is the definition.
(I've seen this in another clue)
'tea-break' is the wordplay.
'break' indicates anagramming the letters.
'tea' anagrammed gives 'EAT'.
'in' acts as a link.
(Other definitions for eat that I've seen before include "and 27: Be humiliated" , "Feed" , "Consume for tea" , "Be corrosive" , "Corrode" .)
