An English school of note (4)
I believe the answer is:
eton
'an english school of note' is the definition.
(I've seen this before)
'of note' is the wordplay.
'of' indicates anagramming the letters (the answer comes from or 'of' the letters).
'note' with letters rearranged gives 'ETON'.
(Other definitions for eton that I've seen before include "Easy to understand" , "Town on the Thames noted for its school" , "Berkshire public school" , "collar, perhaps?" , "Berkshire town" .)
