Etymology

The word "boarder" derives from the noun "board," which originally referred to a flat piece of wood (Old English bord). Over time, "board" expanded to include meanings like "table" (where meals are served) and "deck of a ship." The suffix "-er" denotes a person associated with an action or object. Thus, "boarder" initially described someone who received meals at a table (lodging sense) and later extended to sports involving boards (e.g., snowboarder).
