A cautionary tale about car that's within one's budget (10)
I believe the answer is:
affordable
'within one's budget' is the definition.
I can't tell whether this defines the answer.
'a cautionary tale about car' is the wordplay.
'cautionary tale' becomes 'fable' (I've seen this in another clue).
'about' is an insertion indicator.
'car' becomes 'ford' (Ford is a make of car).
'fable' enclosing 'ford' is 'ffordable'.
'a'+'ffordable'='AFFORDABLE'
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for affordable that I've seen before include "sustainable" , "Reasonably priced" , "being within one's means" , "Within one's ability to pay" , "not breaking the bank" .)
