Etymology: Beryllium is the element, and its name comes from the mineral beryl, the gemstone family that includes emerald and aquamarine. The mineral's own name reaches back to ancient Greek "bḗrullos", which the Romans borrowed as "bēryllus". Chemists took the Latin form "bēryllium" when they named the element, because it was found as a key component of beryl. The element was named by analogy with the mineral, so the name points back to the gem rather than to any property of the metal itself. "Berylliums" is simply the plural of "beryl­lium", used when referring to more than one sample or more than one kind of this element, such as separate batches or distinct compounds containing it. The plural is a regular English formation and carries no separate history.

Synonyms: beryllium atoms, beryllium elements
