Accolade following a tenor's virtue (9)
I believe the answer is:
attribute
'virtue' is the definition.
(thesaurus)
'accolade following a tenor's' is the wordplay.
'accolade' becomes 'tribute' (I've seen this before**).
'following' is a charade indicator (letters next to each other).
'tenor' becomes 't'.
'a'+'t'='at'
'tribute' after 'at' is 'ATTRIBUTE'.
(Other definitions for attribute that I've seen before include "Ascribe, impute" , "Credit - property" , "Ascribe (to a cause)" , "A special characteristic" , "Assign" .)
