Spooner's freezing ear is a nuisance in the street (9)
I believe the answer is:
litterbug
'street' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for litterbug that I've seen before include "One leaving papers around" , "filthy devil" , "Person wilfully dropping rubbish" , "Person dropping refuse in public places" , "One likely to drop" .)
