I'm a little stuck... Click here to teach me more about this clue!

'privileged pupil' is the definition.
'etonian' can be an answer for 'pupil' (I've seen this before). I am not certain of the 'privileged' bit.

'english nation's thrown out' is the wordplay.
'english' becomes 'e' (abbreviation).
'thrown out' indicates an anagram.
'nation' with letters rearranged gives 'tonian'.
'e'+'tonian'='ETONIAN'

Can you help me to learn more?

(Other definitions for etonian that I've seen before include "Pupil at posh English school" , "Public school boy" , "Public school kid" , "Alumnus of famous English school" , "Relating to one particular school" .)
