Jumped from small car accident (6)
I believe the answer is:
sprang
'jumped' is the definition.
('spring' can be a synonym of 'jump')
'small car accident' is the wordplay.
I cannot quite understand how this works, but
'small' could be 's' (abbreviation - e.g. clothes size) and 's' is found in the answer.
'accident' could be 'prang' (I've seen this before) and 'prang' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'from' acts as a link.
Can you help me to learn more?
(Other definitions for sprang that I've seen before include "Jumped suddenly" , "freed prisoner" , "suddenly developed" , "Leapt foward" , "bounced" .)
