Student wasted an entire November getting expelled (7)
I believe the answer is:
trainee
'student' is the definition.
(I've seen this before)
'wasted an entire november getting expelled' is the wordplay.
'wasted' indicates an anagram.
'november' becomes 'n' (phonetic alphabet: alpha, bravo, charlie etc.).
'getting expelled' indicates named letters should be taken away.
'an'+'entire'='anentire'
'anentire' with 'n' removed is 'aentire'.
'aentire' anagrammed gives 'TRAINEE'.
(Other definitions for trainee that I've seen before include "Apprentice" , "one not yet qualified" , "One being taught a job" , "One taking instruction" , "Person being instructed in work" .)
