Go motoring with a novice? Nonsense! (6)
I believe the answer is:
drivel
'nonsense' is the definition.
(drivel can mean nonsensical speech or writing)
'go motoring with a novice?' is the wordplay.
I cannot quite understand how this works, but
'go' could be 'drive' (driving is a kind of going) and 'drive' is found in the answer.
'novice?' could be 'l' (as in a learner driver with L-plates on their car) and 'l' is found in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for drivel that I've seen before include "Claptrap" , "Silly talk, twaddle" , "Worthless talk" , "Worthless, foolish nonsense" , "Nonsense, garbage" .)
