One driven with some lack of care? (3)
I believe the answer is:
car
This clue might be a double definition.
'one driven with some lack' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'care?' is the second definition.
(car care is a kind of care)
'of' acts as a link.
Can you help me to learn more?
(Other definitions for car that I've seen before include "Hatchback, say?" , "Railway carriage; vehicle" , "Means of transport" , "saloon perhaps" , "Automobile" .)
