Car wrecked in bend (3)
I believe the answer is:
arc
'bend' is the definition.
(arcing is a kind of bending)
'car wrecked' is the wordplay.
'wrecked' indicates an anagram.
'car' with letters rearranged gives 'ARC'.
'in' is the link.
(Other definitions for arc that I've seen before include "Semi-circle" , "Bend" , "A curve for Joan of . . ." , "Car (anag.)" , "cut off from the circle" .)
