Morphology

tritium = trit + ium

Contains the combining form 'trit-' (third) plus the chemical noun-forming suffix '-ium'; the 'third' element is visible but the specific meaning 'a hydrogen isotope' is specialized and not fully derivable by an average B1 learner.

Etymology

The word tritium comes from the root tri- meaning 'three', as in triangle or trio, and the element ending -ium. That's why it names a form of hydrogen whose core has one proton and two neutrons, making it 'hydrogen number three'.
