Cardboard is formed from "card" (from Latin "carduus", meaning thistle, referring to the plant fibers used) and "board" (from Old English "bord", meaning a flat piece of material). The word "cardboard" refers to a flat material made from pressed plant fibers, typically used for making boxes and other items.
Think of 'card' as referring to plant fibers and 'board' as a flat piece, which helps you remember that cardboard is a flat material made from pressed plant fibers.
