Puritan translation of Latin is circumspect (10)
I believe the answer is:
prudential
'circumspect' is the definition.
(thesaurus)
'puritan translation of latin' is the wordplay.
'puritan' becomes 'prude' (synonyms).
'translation of' indicates anagramming the letters (translate can mean to transform).
'latin' with letters rearranged gives 'ntial'.
'prude'+'ntial'='PRUDENTIAL'
'is' acts as a link.
(Other definitions for prudential that I've seen before include "Canny" , "With due care" , "exercising sound judgement" .)
