Jolly good sort of purse (5)
I believe the answer is:
super
'jolly good' is the definition.
(I've seen this before)
'sort of purse' is the wordplay.
'sort of' is an anagram indicator.
'purse' anagrammed gives 'SUPER'.
(Other definitions for super that I've seen before include "Peerless" , "Prefix meaning over or extremely" , "Incomparable" , "Excellent; police officer" , "of high quality" .)
