Hold funeral sadly banning students? It's without precedent (7-2)
I believe the answer is:
unheard-of
'without precedent' is the definition.
(I've seen this in another clue)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for unheard-of that I've seen before include "Unknown - novel" , "Fear hound being not previously known" , "Previously unknown" , "Inconceivable" , "Without precedent" .)
