IPA: //ˈdrɛd.nɔt//
KK: /ˈdrɛdˌnɔt/
A type of large battleship that is heavily armed and designed for naval warfare, typically equipped with powerful guns.
The navy launched a new dreadnought that was the most advanced ship in its fleet.
Dreadnought is formed from "dread" (from Old English "dræd", meaning fear) and "nought" (from Old English "nōwiht", meaning nothing). The term originally referred to a ship that was not afraid of anything, particularly in battle, hence a ship that could withstand or face any threat.
Think of 'dread' as fear and 'nought' as nothing — together they describe something that has no fear, like a powerful ship that faces all challenges.
