Smashed the car against an outbuilding (7)
I believe the answer is:
crashed
'smashed the car against an outbuilding' is the definition.
I can't judge whether this defines the answer.
'smashed the car against an outbuilding' is the wordplay.
'smashed' indicates anagramming the letters.
'against' means one lot of letters go next to another.
'an outbuilding' becomes 'shed' (outbuilding in a garden).
'car' anagrammed gives 'cra'.
'cra'+'shed'='CRASHED'
Can you help me to learn more?
(Another definition for crashed that I've seen is " Collided or fell violently".)
