IPA: /ˈɛərˌboʊt/
KK: /ˈɛrˌboʊt/
A type of boat that has a flat bottom and is powered by a large propeller, allowing it to travel over shallow water and swamps.
The airboat glided smoothly over the swamp waters, its propeller whirring loudly.
Airboat is formed from "air" (from Old English "aer", meaning the atmosphere or sky) and "boat" (from Old English "bat", meaning a small vessel for traveling on water). The word "airboat" refers to a type of boat designed to travel over water and land, often using air propulsion.
Think of 'air' as the atmosphere and 'boat' as a vessel — an airboat is a vessel that travels over the air and water.
