Forms

microbe m (plural microbes)[1]

Etymology

The surgeon Charles Sédillot coined it in 1878 from Ancient Greek μικρός (mikrós, “small”) + βίος (bíos, “life”), meaning literally “small life, small living organism”.[2][3][1] Bloch and Wartburg and the Grand Robert instead take it from the Greek compound μικρόβιος (mikróbios, “short-lived”), and the GLLF likewise glosses the compound as “having a short life”.[4][5][6] Etymonline notes that the word was criticized as badly formed, since in Greek such a compound would mean “short-lived”.[7]

Earliest recorded meaning

Sédillot introduced it in 1878 in the weekly reports of the Académie des sciences, for the microscopic organisms that cause disease and putrefaction.[2][3]

Semantic evolution

At first microbe named every organism invisible to the naked eye that caused disease or rot, including what are now called viruses, where today one says micro-organisme, a word from 1876; in modern terminology it is restricted to a single-celled, disease-causing micro-organism.[3][8] Since 1888 it has also been a familiar word for a small, puny person or a child.[2][3][6]

Most of its derivatives arose with Pasteur's discoveries: microbiologie (1883), properly a compound of microbe rather than of micro- and biologie, and the adjective microbien (1888).[3] English took microbe from French in 1878.[7]
