Dicky Antoine a privileged pupil (7)
I believe the answer is:
etonian
'a privileged pupil' is the definition.
'etonian' can be an answer for 'pupil' (I've seen this before). I'm not sure about the 'a privileged' bit.
'dicky antoine' is the wordplay.
'dicky' indicates an anagram (dicky can mean ill or non-functioning).
'antoine' with letters rearranged gives 'ETONIAN'.
Can you help me to learn more?
(Other definitions for etonian that I've seen before include "Public schoolboy" , "English student" , "Pupil at posh English school" , "Public school pupil" , "One educated at famous public school" .)
