Public school characters regularly expelled from West Point (4)
I believe the answer is:
eton
'public school' is the definition.
(Eton College)
'characters regularly expelled from west point' is the wordplay.
I cannot quite see how this works, but
'from' could be 'e' (I've seen this in other clues) and 'e' is present in the answer.
'point' could be 'n' (N is an example) and 'n' is found in the answer.
The remaining letters 'to' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for eton that I've seen before include "academic institution" , "Posh college" , "Famous English public school" , "Public school near Windsor" , "Town on the Thames noted for its school" .)
