A car's logbook? (13)
I believe the answer is:
autobiography
'a car's logbook?' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'car's logbook?' is the wordplay.
I cannot quite understand how this works, but
'car' could be 'auto' (automobile) and 'auto' is located in the answer.
The remaining letters 'biography' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for autobiography that I've seen before include "Person's life story written by the subject" , "Personal account of one's life" , "A person's account of their life" , "Memoirs" , "Literary genre" .)
