Fiberboard → It is formed from "fiber" (from Latin *fibra*, meaning a thread or filament) and "board" (from Old English *bord*, meaning a flat piece of material). The word "fiberboard" refers to a board made from fibers, typically used in construction and furniture.
Think of 'fiber' as a thread or filament that is used to create a flat 'board' — that's why fiberboard is a board made from fibers.
