Morphology
thortveitite = Thortveit (semi-transparent) = thortveit + ite
The suffix '-ite' signals a mineral, so learners can guess it names a mineral, but the eponymic base 'Thortveit' gives no clue to composition.
Etymology
Thortveitite joins a name, Thortveit, with the mineral ending -ite, which means 'rock' or 'stone'. So thinking of it as 'Thortveit's rock' gives a clear image and helps you remember it is a rare mineral and a source of scandium.
