Morphology
anthracite = anthrac + ite
The element 'anthrac-' is a Greek combining form (not a standalone English word) and '-ite' is a mineral-forming suffix; knowing common English words does not allow a learner to infer the meaning of 'anthracite'.
Etymology
The word anthracite comes from the Greek word anthrax meaning 'coal' or 'charcoal', and the ending -ite was later used to name types of rocks. So, anthracite is literally a 'coal rock', a hard, high-grade coal that burns slowly with little smoke.
