Refusal to make any change (3)
I believe the answer is:
nay
'refusal' is the definition.
(I've seen this before)
'any change' is the wordplay.
'change' indicates anagramming the letters.
'any' anagrammed gives 'NAY'.
'to make' is the link.
(Other definitions for nay that I've seen before include "Archaic negative" , "even" , "disagreement" , "Negative response" , "Indeed" .)
