Brief manifestations of grievance, etc. (5)
I believe the answer is:
demos
'brief manifestations' is the definition.
The answer and definition can be both related to communication as well as being plural nouns.
Maybe you can see a link between them that I can't see?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for demos that I've seen before include "mass rallies?" , "protests" , "The people (Greek)" , "The populace" , "masses" .)
