Grand to have a new purse (5)
I believe the answer is:
super
'grand' is the definition.
(thesaurus)
'a new purse' is the wordplay.
'a new' indicates anagramming the letters.
'purse' anagrammed gives 'SUPER'.
'to have' acts as a link.
(Other definitions for super that I've seen before include "of high quality" , "Outstanding" , "Peachy" , "Peerless" , "Smashing, terrific" .)
