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 an anagram (translate can mean to transform).
'latin' with letters rearranged gives 'ntial'.
'prude'+'ntial'='PRUDENTIAL'
'is' is the link.
(Other definitions for prudential that I've seen before include "Canny" , "With due care" , "exercising sound judgement" .)
