Linguistic Note on Potassium
The word potassium derives from the word potash, from which potassium was first extracted.
Potash is a general name for the salts of potassium, manufactured in pre-industrial times from the ash of plants, processed in a pot.
Its symbol $\text K$ derives from the neo-Latin kalium, itself deriving from the Arabic word القَلْيَه (al-qalyah) meaning plant ashes.
