Debonair, making a gentle change (7)
I believe the answer is:
elegant
'debonair' is the definition.
(thesaurus)
'a gentle change' is the wordplay.
'change' is an anagram indicator.
'a'+'gentle'='agentle'
'agentle' is an anagram of 'ELEGANT'.
'making' is the link.
(Other definitions for elegant that I've seen before include "Ingenious" , "Modish" , "Debonair, stylishly dressed" , "Refined gracefulness" , "luxurious style?" .)
