Morphology

anthophyllite = antho + phyll + ite

A technical mineral name built from Greek combining forms and the mineral suffix '-ite'; the components are not standalone English words and the meaning is not inferable to an average B1 learner.

Etymology

Anthophyllite comes from Greek roots anthos 'flower' and phyllon 'leaf', and the phyll part is the same you see in chlorophyll. The mineral was named this because its crystals often look like small leaves or flowers, which helps explain why this brown-green mineral is called anthophyllite.
