Root Explanation

Onboard is formed from "on" (meaning in a position of) and "board" (from Old English "bord", meaning a plank or flat surface). The word "onboard" means to be in a position on a vehicle or vessel, typically referring to being inside or part of it.

Memory Tip

Think of being 'in a position of' ('on') a 'flat surface' ('board') — that's why onboard means being inside or part of a vehicle.
