The story of the word

Microbe was coined in French in 1878 by the surgeon Charles Sédillot, who wanted one short word to replace the competing terms then in use, and microbiology followed within a decade. Purists complained at once that the compound literally says small life rather than small living thing, and that it should have been microbiote. Sédillot's version won because it was easier to say.
