Virtuous sort sat around at home (5)
I believe the answer is:
saint
'virtuous sort' is the definition.
(I've seen this in another clue)
'sat around at home' is the wordplay.
'around' indicates putting letters inside.
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'sat' going around 'in' is 'SAINT'.
(Other definitions for saint that I've seen before include "eg John, Paul or George" , "Scotland's oldest university" , "eg Paul, Peter, Valentine" , "paragon!" , "Holy man" .)
