Season starting late, November, for US student (6)
I believe the answer is:
intern
'us student' is the definition.
(US term for a trainee or student)
'season starting late november' is the wordplay.
'season' becomes 'winter' (winter is a season).
'starting late' means to remove the first letter (the word begins later than normal).
'november' becomes 'N' (phonetic alphabet: alpha, bravo, charlie etc.).
'winter' with its initial letter taken away is 'inter'.
'inter'+'n'='INTERN'
'for' is the link.
(Other definitions for intern that I've seen before include "to keep under lock and key" , "put in jail" , "Confine as a prisoner" , "Work experience trainee" , "Shut up" .)
