Hoverboat

Part of speech: noun

Definitions

1. A watercraft that rises above the surface by forcing air downward beneath it, allowing movement over water or land with reduced friction
2. A vessel that floats on a pressurized layer of air rather than sitting in the water, enabling it to glide smoothly across wet or flat terrain
3. A boat-like craft that hovers just above water or ground by means of an air cushion system, permitting swift travel with minimal drag

Etymology: A hoverboat is simply a compound of "hover" and "boat," and its meaning comes straight from those two parts. "Boat" descends from Old English "bāt," a word for a small vessel that has stayed in the language for more than a thousand years. "Hover" entered English in Middle English with the sense of staying suspended in one place, as a bird does in the air, or lingering nearby. Its deeper origin is uncertain. The first part of the compound describes the craft's defining trick. Instead of pushing through water, it rides on a cushion of air that holds it just above the surface, so the vessel seems to float in place. The term belongs to the same family as "hovercraft," which describes the broader class of air-cushion vehicles.

Synonyms: hydrofoil, speedboat
