Unoriginal musical chicken almost making a comeback (9)
I believe the answer is:
imitative
'unoriginal' is the definition.
(similar in meaning)
'musical chicken almost making a comeback' is the wordplay.
'musical' becomes 'evita' (Andrew Lloyd Webber musical).
'chicken almost' becomes 'timi' (I can't explain this - if you can you should believe this answer much more).
'making a comeback' is a reversal indicator.
'evita'+'timi'='evitatimi'
'evitatimi' backwards is 'IMITATIVE'.
Can you help me to learn more?
(Other definitions for imitative that I've seen before include "Mimicking or onomatopoeic" , "Echoing" , "is like an ape" , "Copying" , "Following a model" .)
