Morphology

calcium + sulfate

The compound name 'calcium sulfate' directly denotes the sulfate salt/compound of the element calcium; its meaning is compositionally derived from 'calcium' (the element) + 'sulfate' (the SO4^2− salt group). This follows standard, cross-linguistic chemical naming conventions, so a learner who knows both constituents can infer it refers to the inorganic compound (e.g., gypsum), making it transparent.

Etymology

Calcium sulfate comes from two parts: calcium, from a Latin word for 'lime', and sulfate, from 'sulfur'. So the name tells you it is a salt of calcium and sulfur, the white mineral 'gypsum' that is used in plaster and some foods.
