Complete the sentence with the correct form of the verb in brackets: "He ____ (wind) the old clock every Sunday evening until it finally stopped."

Explication

Wind meaning to turn or coil is irregular and runs wind — wound — wound, so a finished habit in the past takes wound. The spelling wound also belongs to a separate regular verb meaning to injure somebody, whose past is wounded, so writing wounded here would turn a sentence about turning a key into one about causing harm.
