Somehow censure it for hundreds of years (9)
I believe the answer is:
centuries
'hundreds of years' is the definition.
(I've seen this before)
'somehow censure it' is the wordplay.
'somehow' indicates an anagram.
'censure'+'it'='censureit'
'censureit' anagrammed gives 'CENTURIES'.
'for' acts as a link.
(Other definitions for centuries that I've seen before include "Periods of 100 years" , "Censure it for hundreds of years" .)
