Etymology: Kerargyrite is a mineral whose name is built from two Greek elements, and the spelling "kerargyrite" is an alternative to "cerargyrite." The first part comes from Ancient Greek "kéras," meaning "horn," a reference to the mineral's horn-like, waxy appearance. The second part, "argyr-," comes from Greek "árgyros," meaning "silver," which points to the metal the mineral contains. The ending "-ite" is the standard suffix used in mineral names, so the whole word is a modern scientific coinage that combines the two Greek roots with that suffix. Its meaning is therefore literal: a silver mineral with a horn-like look.
