Virtue of good people (5)
I believe the answer is:
grace
'virtue' is the definition.
(thesaurus)
'good people' is the wordplay.
'good' becomes 'g' (abbreviation).
'people' becomes 'race' (people can mean a national group or race).
'g'+'race'='GRACE'
'of' is the link.
(Other definitions for grace that I've seen before include "Honour" , "Elegance; blessing" , "Meal blessing" , "Comeliness" , "Before dinner, one may have this" .)
