When a car crashes, it's bent (3)
I believe the answer is:
arc
'bent' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'when a car crashes' is the wordplay.
'car' can be anagrammed to 'ARC'.
But, I'm unsure how this is indicated.
'it's' is the link.
Can you help me to learn more?
(Other definitions for arc that I've seen before include "Light" , "Luminous electrical discharge" , "Bend" , "bends?" , "section of Circle Line" .)
