Which word means to put out or douse something, often a fire?

The term that means to put out or douse something, especially a fire, is "extinguish." This word is commonly used in the context of fire safety and management, referring specifically to the act of stopping or putting out flames. When firefighters arrive at a scene, their primary objective is to extinguish any active fires to prevent further damage and ensure safety. "Extinguish" captures both the physical action of snuffing out fire and the broader concept of eliminating something that is active or uncontrolled, making it a precise word in this context.

On the other hand, the other options do not relate to putting out a fire. "Feign" means to pretend or fake something, "exuberant" describes lively energy or enthusiasm, and "falter" refers to hesitating or losing strength, none of which convey the idea of extinguishing a fire.
