Place one surrendered to accommodate one novice driver as carriage guide (9)
I believe the answer is:
postilion
'carriage guide' is the definition.
(person guiding a horse-drawn carriage)
'place one surrendered to accommodate one novice driver' is the wordplay.
I cannot really understand how this works, but
'place' could be 'post' (synonyms) and 'post' is found within the answer.
'one' could be 'li' (I've seen this in other clues) and 'li' is found within the answer.
The remaining letters 'ion' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'as' acts as a link.
(Another definition for postilion that I've seen is " Rider of near-side coach horse".)
