Imaginative chapter concerning Evita returning (8)
I believe the answer is:
creative
'imaginative' is the definition.
(similar in meaning)
'chapter concerning evita returning' is the wordplay.
'chapter' becomes 'c' (abbreviation).
'concerning' becomes 're' (both can mean on a particular topic).
'returning' says the letters should be written backwards.
'evita' backwards is 'ative'.
'c'+'re'+'ative'='CREATIVE'
(Other definitions for creative that I've seen before include "Innovative in reactive way" , "Artistic, able to make new things" , "Involving original ideas" , "Inventive, artistic" , "Full of ideas" .)
