Morphology

anhydrite = anhydrous (semi-transparent) = an + hydr + ite

Forming a mineral name from an adjective meaning 'without water' is clear in principle, but the Greek combining form 'hydr' and the negative prefix 'an-' are not transparent to many B1 learners.

Etymology

Anhydrite comes from the parts an- 'not' and hydr- 'water', like in hydrate, and the ending -ite often marks a mineral. So anhydrite literally means 'without water', which explains why it is a dry mineral used in plasters, cements, and as a drying agent.
