Bottle shown by male driver? (6)
I believe the answer is:
carboy
'bottle' is the definition.
(carboy is a kind of bottle)
'male driver?' is the wordplay.
I cannot quite see how this works, but
'male' could be 'boy' (boy is a kind of male) and 'boy' is found in the answer.
The remaining letters 'car' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'shown by' acts as a link.
Can you help me to learn more?
(Other definitions for carboy that I've seen before include "Large bottle in a protective container - by Cora (anag)" , "Large bottle for holding corrosive liquids" , "Large bottle for acids" , "Acid container of young automobile attendant?" , "a lot of bottle?" .)
