Something that is warm has some heat but not enough to be hot.

Warm clothes and blankets are made of a material such as wool which protects you from the cold.

Warm colours have red or yellow in them rather than blue or green, and make you feel comfortable and relaxed.

A warm person is friendly and shows a lot of affection or enthusiasm in their behaviour.

If you warm a part of your body or if something hot warms it, it stops feeling cold and starts to feel hotter.

If you warm to a person or an idea, you become fonder of the person or more interested in the idea.
