Morphology
pallasite = Pallas (semi-transparent) = pallas + ite
Formally built from the proper name 'Pallas' plus the mineral-forming suffix '-ite', but the specific meaning 'type of meteorite' is specialized and relies on knowledge of the suffix.
Etymology
Pallasite is named after the scientist Pallas, and the ending -ite means 'rock' or 'mineral', like in granite. So a pallasite is literally 'Pallas's rock', a type of meteorite with green olivine crystals set in metal.
