Waggoner → It is formed from "wag" (from Old English *wagian*, meaning to move or sway) and "-oner" (a suffix indicating a person who performs an action). The word "waggoner" refers to a person who drives or operates a wagon, thus someone who moves or sways a wagon.
Think of someone who 'moves' ('wag') a 'wagon' — that's why a waggoner is a person who drives a wagon.
