Snuffing refers to the act of extinguishing a flame, often used in the context of candles. This can be done by blowing out the flame or using a snuffer, a small tool designed to safely put out the fire without creating smoke or splatter. In a broader sense, snuffing can also describe the act of suppressing or ending something abruptly, such as a conversation or an idea. This usage is often metaphorical, indicating the cessation of an activity or thought process, similar to how a flame is snuffed out.
