The nose of a car? (6)
I believe the answer is:
hooter
'the nose' is the definition.
(hooter is a kind of nose)
'of a car?' is the wordplay.
I cannot really see how this works, but
'of' could be 'o' and 'o' is located in the answer.
'car?' could be 't' and 't' is located in the answer.
The remaining letters 'hoer' is a valid word which might be clued in a way I don't see.
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" .)
