KK: /ˈsplæʃbɔrd/
A board or structure used to prevent splashes of water, mud, or other substances from affecting an area, often found on vehicles or boats.
The splashboard on the truck kept the mud from splattering onto the passengers.
The word 'splashboard' is formed from 'splash' (from Middle English *splashen*, meaning to scatter liquid) and 'board' (from Old English *bord*, meaning a flat surface or plank). A splashboard refers to a board that protects against splashes, particularly in a vehicle or on a boat.
Think of 'splashing' water and a 'board' that keeps it contained — a splashboard is a board that prevents splashes.
