Etymology
The word 'autoclave' is a modern scientific term with a literal meaning of "self-locking." It was coined in French in the 19th century from the Greek prefix auto- ("self") and the Latin root clavis ("key"). The original French device was named for its self-sealing or self-locking mechanism, a safety feature where the steam pressure itself secures the door. Over time, the term's primary association shifted from the locking mechanism to the device's core function of sterilization using pressurized steam, a process that became fundamental in microbiology and medicine.
