Rubbish motorist finally making left instead of right (6)
I believe the answer is:
drivel
'rubbish' is the definition.
(I've seen this before)
'motorist finally making left instead of right' is the wordplay.
I cannot quite understand how this works, but
'left' could be 'l' (common abbreviation) and 'l' is found within the answer.
'right' could be 'r' (common abbreviation) and 'r' is found within the answer.
The remaining letters 'dive' 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 drivel that I've seen before include "Slaver" , "Worthless talk" , "Spoken nonsense" , "Claptrap" , "Nonsense, garbage" .)
