Origin of 'magnetite'

Main points about word origin

  • The name comes from 'Magnes', an ancient Greek word for magnet or lodestone โ€“ a naturally magnetized piece of iron.
  • The suffix '-ite' is commonly used in mineralogy to denote natural minerals and rocks.
  • Historically, the word evolved in languages such as Latin and Old French before making its way into modern English.

The word 'magnetite' comes from the German term 'Magnetit', which was coined by Johann Gottlob Lehmann in 1770. The mineral has been known since ancient times and was used in compasses by the ancient Greeks and Chinese. Magnetite is named after the magnetic properties it exhibits, derived from the Greek word 'magnรญtis lรญthos', meaning 'Magnesian stone'.
