A type of boat that is kept on a ship and used for safety in case the ship needs to be abandoned or for rescuing people in emergencies.
The crew quickly boarded the lifeboat after the captain ordered an evacuation.
Lifeboat → It is formed from "life" (from Old English "līf", meaning existence or living) and "boat" (from Old English "bāt", meaning a small vessel for traveling on water). The word "lifeboat" refers to a boat designed to save lives, especially in emergencies at sea.
Think of a vessel that is meant to preserve 'life' — that's why a lifeboat is a boat for saving lives.
