Show what discontented groups do (11)
I believe the answer is:
demonstrate
'show' is the definition.
(I know that show can be written as demonstrate)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for demonstrate that I've seen before include "Review" , "Take part in public protest" , "English floozies returning, led by villainous character" , "Show or display" , "Prove, show" .)
