Insult; suppress (3,4)
I believe the answer is:

'insult' is the first definition.
(thesaurus)
'suppress' is the second definition.

(Other definitions for put down that I've seen before include "Make record" , "Record - suppress - disparage" , "Humiliating remark" , "Recorded - snub" , "crushing snub" .)
