After English pass, on to enter quality school (4,7)
I believe the answer is:
eton college
'school' is the definition.
(I've seen this before)
'after english pass on to enter quality' is the wordplay.
I cannot really see how this works, but
'english' could be 'e' (abbreviation) and 'e' is located in the answer.
'pass' could be 'col' (col is a term for a mountain pass) and 'col' is present in the answer.
'on' could be 'leg' (cricket term) and 'leg' is located in the answer.
'to' is within the answer.
The remaining letters 'ne' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for eton college that I've seen before include "School near Windsor" , "Famous educational establishment" , "Public school founded by Henry V I" .)
