Morphology

calcium + hydride

The term denotes the hydride of calcium and is compositionally built from 'calcium' (the element) + 'hydride' (a compound containing hydrogen), so a learner who knows both constituents can infer it refers to a calcium–hydrogen compound (CaH2). Although technical chemistry vocabulary, the naming follows standard, cross-linguistic chemical composition rules, making the meaning predictable from the parts.

Etymology

The compound calcium hydride gets its name from its parts: the metal calcium and hydride, a word that tells you it contains 'hydrogen'. So the name fits its current meaning: it is a gray powder of calcium that gives off 'hydrogen' when it meets water.
