'Criminal is evil,' CID educated (9)
I believe the answer is:
civilised
'educated' is the definition.
('educated'->'civilized' is in my internal thesaurus and 'ize'->'ise')
'criminal is evil cid' is the wordplay.
'criminal' indicates an anagram.
'is'+'evil'+'cid'='isevilcid'
'isevilcid' is an anagram of 'CIVILISED'.
(Other definitions for civilised that I've seen before include "Socially and culturally developed" , "Developed, cultured" , "Polite - refined" .)
