Saleslady → It is formed from "sales" (from Old English *sælan*, meaning to give or sell) and "lady" (from Old English *hlæfdige*, meaning a woman of high social status). The word "saleslady" refers to a woman who sells goods or services, combining the act of selling with the designation of a woman.
