Warm describes something that has a comfortable level of heat, not too hot and not cold.
“Warm” comes from Old English “wearm,” which meant “warm, hot, cheerful.” It is tied to old Germanic roots about warmth and comfort.
We use “warm” not just for temperature but also for feelings, like a “warm smile” or a “warm welcome.” Your brain links physical warmth with emotional kindness more than you might realize.
