Surface Forms

kaolinite singular

Morphology

kaolinite = kaolin (transparent) = kaolin + ite

Formed directly from the noun 'kaolin' with the common mineral-forming suffix '-ite', so the meaning is directly a mineral related to kaolin.

Etymology

Kaolinite comes from the Chinese place name Gaoling, meaning 'high ridge'. The fine white clay from that ridge was called kaolin, and kaolinite comes from kaolin plus the mineral ending -ite, so today it means the white clay mineral used in porcelain and ceramics.
