Sneer at record (3,4)
I believe the answer is:
put down
This clue is a double definition.
'sneer at' is the first definition.
(thesaurus)
'record' is the second definition.
(I've seen this before)
(Other definitions for put down that I've seen before include "Make record" , "drop" , "Quell - crushing remark (3,4;3-4)" , "Quell; snub" , "Record - suppress - disparage" .)
