Hate starting November badly (5)
I believe the answer is:
venom
'hate' is the definition.
(venom is a kind of hate)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for venom that I've seen before include "Bitter malice" , "Snake's poison" , "Poison; malice" , "Virulent feeling" , "Toxic substance" .)
