quartzite

the word 'quartzite' is a modern scientific compound formed in english. its first element, 'quartz', entered english from german mining terminology, which itself likely borrowed from a west slavic source, possibly related to the czech word 'tvrdý' meaning 'hard', reflecting the mineral's characteristic property. the second element, '-ite', is a suffix of greek origin, adopted via latin and french into english as a standard denoter for rocks and minerals. the term's construction follows a transparent pattern in geological nomenclature, where the base mineral name is combined with '-ite' to indicate a rock primarily composed of that mineral. thus, 'quartzite' literally and logically means 'a rock of or resembling quartz', directly describing its dominant composition and metamorphic origin.

Structure: quartz + ite quartz: from german 'quarz', of slavic origin; denotes the mineral quartz. ite: from greek '-itēs' (via latin '-ita', french '-ite'); a suffix forming nouns, especially names of minerals and rocks.
