Big wheels back from crucial meeting with one reserve depleted (10)
I believe the answer is:
limousines
'big wheels' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Maybe there's an association between them I don't understand?
'back from crucial meeting with one reserve depleted' is the wordplay.
I cannot really understand how this works, but
'from' could be 'in' (I've seen this in other clues) and 'in' is found in the answer.
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for limousines that I've seen is " cars".)
