We hear school meals should be this (5)
I believe the answer is:
eaten
'meals should be this' is the definition.
The definition suggests a singular noun but the answer is not.
'we hear school' is the wordplay.
'we hear' shows a homophone (sound like).
'school' becomes 'eton' (famous UK public school).
'eton' sounds like 'EATEN'.
Can you help me to learn more?
(Other definitions for eaten that I've seen before include "Scoffed" , "absorbed in the system" , "used for food" , "Consumed" , "Taken into the body as food" .)
