Etymology: Eubacteria is a taxonomic name built from Greek parts: "eu-", meaning "true" or "good," and "baktērion," a diminutive of "baktēria," meaning "staff" or "walking stick," a reference to the rod shape of many early-observed microbes. The name was coined by scientists studying bacteria, who wanted a label for what they saw as the "true" bacteria, set apart from other groups once considered bacterial. The Greek roots are ancient, but the combined scientific name is a modern invention, not something classical writers used. The adjective is simpler. English took the taxonomic name and added the suffix "-al," the common English ending meaning "relating to," giving a word meaning "of or relating to the eubacteria." The "-al" ending itself comes through Latin "-ālis" and, via Old French, arrived in Middle English, so it is an old and very productive English suffix.
