Expectation for particular ballet's finale (8)
I believe the answer is:
prospect
'expectation' is the definition.
(I know that expectation can be written as prospect)
'for particular ballet's finale' is the wordplay.
'for' becomes 'pro' (as in being 'pro' something).
'particular' becomes 'spec' (I've seen this in another clue).
'finale' indicates one should take the final letters.
The last letter of 'ballet' is 't'.
'pro'+'spec'+'t'='PROSPECT'
(Other definitions for prospect that I've seen before include "Chance of success" , "Outlook or panorama" , "Extensive landscape" , "Possibility of future success" , "Possibility; wide view" .)
