Potboy → The word is formed from "pot" (from Old English *pott*, meaning a container or vessel) and "boy" (from Old English *bōia*, meaning a young male). A potboy originally referred to a young male servant who worked in a kitchen, often responsible for handling pots and cooking vessels.
Think of a young male ('boy') who works with cooking containers ('pot') — that's why a potboy is a kitchen helper.
