Ridicules one who eats too quickly (6)
I believe the answer is:
scoffs
'ridicules' is the definition.
(scoff is a kind of ridicule)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for scoffs that I've seen before include "'Jeers, scorns (6)'" , "Speaks contemptuously or eats greedily" , "Ridicules or eats slangily" , "Ridicules - or drinks quickly" , "Mocks or drinks greedily" .)
