Original copyright over revolutionary Queen musical withdrawn (8)
I believe the answer is:
creative
'original' is the definition.
(associated in meaning)
'copyright over revolutionary queen musical withdrawn' is the wordplay.
'copyright' becomes 'C' (as in the copyright symbol, a C in a circle).
'over' becomes 're'.
'revolutionary queen musical' becomes 'evita' (I can't justify this - if you can you should give a lot more credence to this answer).
'withdrawn' says the letters should be written in reverse.
'evita' backwards is 'ative'.
'c'+'re'+'ative'='CREATIVE'
Can you help me to learn more?
(Other definitions for creative that I've seen before include "Reactive in artistic manner" , "Showing imagination" , "Imaginative, artistic" , "Inventive, artistic" , "Innovative in reactive way" .)
