Etymology: The machine behind "autoclaving" is named for a key that never turns a lock. An autoclave is a sealed vessel that uses pressurised steam to kill microbes, and its name was built in French from "auto-", meaning self, and the Latin "clavis", meaning key. The idea is that the device locks itself shut: the lid is secured by its own pressure, so it closes automatically as it is sealed. The "key" element points to Latin, where "clavis" gave English words like "clavicle" and "clavier", but here it is combined with the Greek-derived prefix to describe the vessel's self-securing closure. The compound is a French technical coinage, so it does not come from classical antiquity. Its modern sense of sterilisation by steam under pressure was built onto the older name, which was attached to the apparatus rather than to any process.
