After a break, come back to answer (6)
I believe the answer is:
rejoin
'answer' is the definition.
(rejoining is a kind of answering)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for rejoin that I've seen before include "Retort" , "renew subscription" , "Return" , "counter" , "Unite again" .)
