'oxyhydrogen' originates from the combination of 'oxygen' and 'hydrogen', where 'oxy-' refers to 'sharp' or 'acid' and 'hydrogen' means 'water-forming'.

'oxyhydrogen' was formed by combining the words 'oxygen' and 'hydrogen' in the 19th century to describe the gaseous mixture used in torches.

Initially, it referred to the gaseous mixture used in scientific experiments, but over time it evolved into its current meaning of a mixture used in welding and cutting.
