Morphology
molybdenite = molybdenum (transparent) = molybden + ite
Formed by adding the mineral-forming suffix '-ite' to the element name 'molybdenum', so knowing the base yields the meaning 'mineral of molybdenum'.
Etymology
Molybdenite comes from the element name molybdenum, which itself comes from the old Greek word molybdos meaning 'lead', because the mineral looks dark and lead-like. The ending -ite shows it is a mineral, as in graphite, so molybdenite is the mineral that contains molybdenum and was named for its lead-like look.
