Teaching English and Latin could flop after lecturers are expelled (9)
I believe the answer is:
education
'teaching' is the definition.
('education' can be a synonym of 'teaching')
I can't explain the rest of the clue.
(Other definitions for education that I've seen before include "Cautioned (anag)" , "Cautioned about learning process" , "New Labour mantra, when repeated" , "A tonic due (anag.)" , "Knowledge acquired by learning and instruction" .)
