Scoffed in school, we hear (5)
I believe the answer is:
eaten
'scoffed' is the definition.
(I've seen this before)
'school we hear' is the wordplay.
'school' becomes 'eton' (famous UK public school).
'we hear' indicates a 'sounds like' (homophone) clue.
'eton' sounds like 'EATEN'.
'in' is the link.
(Other definitions for eaten that I've seen before include "demolished, possibly" , "Taken into the body as food" , "This bread is soon forgotten, it's said" , "corroded" , "Consumed" .)
