Put a restriction on freedom in punishing at Eton (4)
I believe the answer is:
gate
'put a restriction on freedom' is the definition.
I can't judge whether this defines the answer.
'in punishing at eton' is the wordplay.
'in' indicates a hidden word.
'GATE' is hidden within 'punishing at eton'.
Can you help me to learn more?
(Other definitions for gate that I've seen before include "Entrance; street" , "Movable opening" , "Attendance at a sporting event" , "Access here" , "Spectators - entrance" .)
