noun
Usage
What does floorboard mean? A floorboard is one of the usually wooden planks that make up a floor. It usually refers to a board of plywood used to make a subfloor—the rough floor beneath a finished floor. Many houses are constructed using floorboards to create a subfloor, which is then often covered with materials like hardwood, carpet, tile, linoleum, or some form of laminate flooring. The word floorboard means something else in the context of vehicles—it refers to the floor of a car or truck. This sense of the word is the basis of the slang verb floorboard, meaning to press a vehicle’s accelerator (gas pedal) as far down as possible (all the way to the floor) in order to go as fast as possible. The word floor is more commonly used to mean the same thing. Both terms are often followed by it, as in As soon as the light turned green, I floorboarded it so I could get way ahead of all the other cars. Example: I pried up a loose floorboard hoping to find treasure under, but there was just a lot of dust and dirt.
