Terrific change in purse (5)
I believe the answer is:
super
'terrific' is the definition.
(I've seen this in another clue)
'change in purse' is the wordplay.
'change in' indicates anagramming the letters.
'purse' is an anagram of 'SUPER'.
(Other definitions for super that I've seen before include "Outstanding" , "Marvellous, terrific" , "Prefix meaning above or informally great" , "Prefix meaning terrific or great" , "Exceptional" .)
