Etymology: "Corynebacteria" is the plural of "corynebacterium," a name built from Greek roots. The first part, "coryne," is Greek for a club or mace, a reference to the club-like, rod shapes these microbes take under the microscope. "Bacterium" comes from the Greek "baktron," meaning a staff or walking stick, which is why the group's names so often describe rods. The genus name Corynebacterium was formed as a scientific Latinized coinage, a technical label assembled for classification rather than a word with an ancient history. Its use in English is therefore modern, and it was borrowed directly from the international scientific vocabulary used across languages, so the name looks and sounds nearly the same in most scientific writing.
