Condemns ten scenes unexpectedly (9)
I believe the answer is:
sentences
'condemns' is the definition.
('sentence' can be a synonym of 'condemn')
'ten scenes unexpectedly' is the wordplay.
'unexpectedly' indicates an anagram.
'ten'+'scenes'='tenscenes'
'tenscenes' anagrammed gives 'SENTENCES'.
(Other definitions for sentences that I've seen before include "Groups of words as punishments for crimes" , "Judicial punishments or words arrangements" , "Words with grammatical structures" , "Sets of words, or punishments awarded by courts" , "Judicial penalties" .)
