The nose of a car? (6)
I believe the answer is:
hooter
'the nose' is the definition.
(hooter can informally mean someone's nose)
'of a car?' is the wordplay.
I cannot really understand how this works, but
'of' could be 'o' and 'o' is present in the answer.
'car?' could be 't' and 't' is found within the answer.
The remaining letters 'hoer' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for hooter that I've seen before include "One scents" , "Siren, horn; nose" , "Siren; nose (sl.)" , "owl?" , "Car horn or slang nose" .)
