hydrogen (English)
Where does "hydrogen" come from?
The word 'hydrogen' was coined by French chemists Antoine Lavoisier and Louis-Bernard Guyton de Morveau to describe the element that 'brings forth water' when burned. It is formed by combining the Ancient Greek 'húdōr' (water) and the root 'gennáō' (to bring forth), tracing back to the Proto-Indo-European roots for 'water' (*wed-) and 'to be born' (*ǵenh₁-). This creates a literal definition of the gas as the 'water-producer'.
