'vaporizer' originates from the Latin word 'vapor,' meaning 'steam' or 'mist,' combined with the suffix '-izer,' indicating an agent or device.

'vapor' transformed from the Latin word 'vapor' into the Old French word 'vapeur,' and eventually became the modern English word 'vapor' through Middle English.

Initially, it meant 'steam or mist,' but over time it evolved into its current meaning of 'a device that converts substances into vapor.'
