Movement in arts mimics no art that is contrived (11)
I believe the answer is:
romanticism
'movement in arts' is the definition.
'romanticism' can be an answer for 'arts' (romanticism is a kind of arts). I'm unsure of the 'movement in' bit.
'mimics no art that is contrived' is the wordplay.
'that is contrived' is an anagram indicator.
'mimics'+'no'+'art'='mimicsnoart'
'mimicsnoart' is an anagram of 'ROMANTICISM'.
Can you help me to learn more?
(Other definitions for romanticism that I've seen before include "Wagnerian movement" , "Eighteenth century artistic movement" , "Art style" , "Sentimental feeling" .)
