Etymology: "Aerobes" is the plural of "aerobe," a noun for organisms that need oxygen to live. The word is built from two Greek roots: "aḗr," meaning air, and "bíos," meaning life. The first root is ancient and sits behind the Greek word for the lower atmosphere, while the second appears in many modern scientific compounds, such as "biology." The immediate source of the English word is French "aérobie," which combines the same two elements. English took it up with the same sense, so the term describes a life form defined by its relationship to air, specifically the oxygen within it. The plural simply applies that label to the many species that share this need.
