A kettle, sometimes called a tea kettle or teakettle, is a type of pot specialized for boiling water, commonly with a lid, spout, and handle, or a small electric kitchen appliance of similar shape that functions in a self-contained manner. Kettles can be heated either by placing on a stove, or by their own internal electric heating element in the appliance versions. As indicated by its name, the kettle was and is often used as teaware to brew tea or prepare a tisane. Some very modern versions do more than just boil water, and also make the tea and keep it warm.
