A pyre, also known as a funeral pyre, is a structure used for burning a body. The word "pyre" comes from the Greek word for "fire". Pyres are built outdoors. They are usually made from wood. The body is placed on top of the pyre or under it. Then the pyre is set on fire. Pyres are still used for funerals in some parts of the world. They are also used for other types of ceremonies. In those ceremonies, there is a big fire, but a body is not burned. Historically, pyres have also been used to kill people by burning them alive.
