Revolutionary movement putting barrier around platform (7)
I believe the answer is:
dadaism
'revolutionary movement' is the definition.
'Dadaism' can be an answer for 'movement' (Dadaism is an example). I'm not certain of the 'revolutionary' bit.
'barrier around platform' is the wordplay.
I cannot really understand how this works, but
'platform' could be 'dais' (dais is a kind of platform) and 'dais' is found within the answer.
'barrier' could be 'dam' (dam is a kind of barrier) and 'dam' is found within the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'putting' acts as a link.
Can you help me to learn more?
(Other definitions for dadaism that I've seen before include "artistic movement" , "Anti-art movement" , "Early twentieth century art movement" , "Absurd movement" .)
