Where we left a trainee driver at the bus terminus (5)
I believe the answer is:
wells
'driver at the bus terminus' is the definition.
I can't judge whether this defines the answer.
'where we left a trainee' is the wordplay.
I cannot really understand how this works, but
'we' is present in the answer.
'left' could be 'l' (common abbreviation) and 'l' is found in the answer.
'trainee' could be 'l' and 'l' is found within the answer.
A single letter 's' remains 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 wells that I've seen before include "What a boring person might produce" , "Flows upward; small city" , "Author" , "H.G. - - , writer" , "Springs" .)
