Post online and call from branch? (5)
I believe the answer is:
tweet
This clue could be a double definition.
'post online' is the first definition.
'call from branch?' is the second definition.
'tweet' can be an answer for 'call' (I've seen this before). I am unsure of the 'from branch?' bit.
'and' is the link.
Can you help me to learn more?
(Other definitions for tweet that I've seen before include "Message from Trump?" , "little message" , "Chirp of a small bird" , "Bird noise" , "Note from flier" .)
