Subpanel → It is formed from "sub-" (meaning under or below) and "panel" (from Old French *panel*, meaning a flat piece or section). The word "subpanel" refers to a panel that is located under or below another panel, often used in electrical systems.
Think of something that is 'under' ('sub-') another flat section ('panel') — that's why a subpanel is a panel located below another.
