Nine acts rewritten, for example (8)
I believe the answer is:
instance
'example' is the definition.
(synonyms)
'nine acts rewritten' is the wordplay.
'rewritten' indicates anagramming the letters.
'nine'+'acts'='nineacts'
'nineacts' anagrammed gives 'INSTANCE'.
'for' is the link.
(Other definitions for instance that I've seen before include "An insect (anag.)" , "Case - isn't acne (anag)" , "Example or single occurrence of something" , "Particular example" , "A case or example of something" .)
