I would return a social division’s verbal attacks! (9)
I believe the answer is:
'verbal attacks' is the definition.
The definition and answer can be both related to communication as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'i would return a social division's' is the wordplay.
'i would' becomes 'I'd'.
'return' shows that the letters should be reversed in order.
'social division's' becomes 'tribes' (I am not sure about this - if you are sure you should believe this answer much more).
'id' written backwards gives 'di'.
Can you help me to learn more?
(Other definitions for diatribes that I've seen before include "impassioned speeches" , "Harangues" .)
