Root Explanation

Potassium comes from the New Latin 'potassium', which is derived from 'potash' (from Middle Dutch 'potaschen', meaning to leach ashes in a pot). The term 'potash' refers to the ashes of plants that were leached in pots to extract potassium carbonate, which is a key source of potassium. Thus, potassium is named after the process of obtaining it from plant ashes.

Memory Tip

Think of 'potash', which refers to the ashes leached from plants in a pot, to remember that potassium is derived from this process.
