Fake current Lloyd Webber musical with brief interval making a comeback (9)
I believe the answer is:
imitative
'fake' is the definition.
(similar in meaning)
'current lloyd webber musical with brief interval making a comeback' is the wordplay.
'current' becomes 'I' (symbol for electric current).
'lloyd webber musical' becomes 'evita' (musical about Eva Peron).
'with brief interval' becomes 'tim' (I can't justify this - if you can you should give a lot more credence to this answer).
'making a comeback' says the letters should be written backwards.
'evita'+'tim'='evitatim'
'evitatim' back-to-front is 'mitative'.
'i'+'mitative'='IMITATIVE'
Can you help me to learn more?
(Other definitions for imitative that I've seen before include "Apish, emulative" , "is like an ape" , "Echoing" , "Copying" , "Following a model" .)
