A long time to censure it, perhaps (9)
I believe the answer is:
centuries
'a long time to' is the definition.
I can't tell whether this defines the answer.
'censure it perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'censure'+'it'='censureit'
'censureit' with letters rearranged gives 'CENTURIES'.
Can you help me to learn more?
(Other definitions for centuries that I've seen before include "Censure it for hundreds of years" , "Periods of 100 years" .)
