A story about car not breaking the bank (10)
I believe the answer is:
affordable
'not breaking the bank' is the definition.
(I've seen this before)
'a story about car' is the wordplay.
I cannot quite see how this works, but
'a' is found in the answer.
'about' could be 'a' (abbreviation in Chambers) and 'a' is found within the answer.
'car' could be 'ford' (Ford is a make of car) and 'ford' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for affordable that I've seen before include "costing reasonable amount" , "sustainable" , "Within one's ability to pay" , "being within one's means" , "not breaking the bank" .)
