Advertised school dance and noted November cancellation (8)
I believe the answer is:
promoted
'advertised' is the definition.
('promote' can be a synonym of 'advertize')
'school dance and noted november cancellation' is the wordplay.
I cannot really see how this works, but
'dance' could be 'prom' (prom is a kind of dance) and 'prom' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for promoted that I've seen before include "Put up" , "Pushed" , "Advanced" , "Publicised" .)
