A crushing remark you attribute to (3-4)
I believe the answer is:
put-down
I believe this is a double definition.
'a crushing remark' is the first definition.
(I've seen this before)
'attribute to' is the second definition.
(thesaurus)
'you' is the link.
(Other definitions for put-down that I've seen before include "Crushing remark" , "Snub" , "Humiliating remark" .)
