Word origin

The word 'vapour' originated from the Old French word 'vapor', meaning steam or exhalation. It has been used in English since the 14th century to refer to the visible mass of water droplets in the atmosphere. In the 17th century, the term also began to be used in chemistry to describe substances in the gaseous state. Over time, 'vapour' has become a common term in meteorology and science to describe various forms of gaseous substances.
