Sun creed possibly criticised (8)
I believe the answer is:
censured
'criticised' is the definition.
(censuring is a kind of criticising)
'sun creed possibly' is the wordplay.
'possibly' is an anagram indicator.
'sun'+'creed'='suncreed'
'suncreed' anagrammed gives 'CENSURED'.
(Other definitions for censured that I've seen before include "Reproached or criticised" , "Blamed and strongly rebuked" , "Rebuked formally" , "Strongly criticised or condemned" .)
