College of note, perhaps (4)
I believe the answer is:
eton
'college' is the definition.
(Eton College, English private school)
'note perhaps' is the wordplay.
'perhaps' indicates an anagram.
'note' anagrammed gives 'ETON'.
'of' is the link.
(Other definitions for eton that I've seen before include "Posh British public school" , "Place for learning" , "College, collar or crop" , "College in Berkshire" , "learn here?" .)
