Complained when the car ran into some pedestrians (6)
I believe the answer is:
carped
'complained' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for carped that I've seen before include "Complained like goldfish?" , "Raised trivial objections" , "Raised petty objections like goldfish" .)
