Scoffs (6)
I believe the answer is:
sneers
'scoffs' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sneers that I've seen before include "Makes scornful remark, derides" , "Contemptuous or scornful remarks" , "Shows contempt by scornful expression" , "Expresses cynical contempt" , "Jeers, derides" .)
