Etymology: "Hypoxic" is built from "hypoxia," which itself combines the Greek prefix "hypo-," meaning "under" or "below," with "oxia," from "oxys," meaning "sharp" or, in the chemical sense of later coinage, "oxygen." The adjective then adds the familiar "-ic" suffix that turns a noun into a descriptive term, so a hypoxic tissue is one suffering from a shortage of oxygen. The source also allows an alternative split, "hyp-" plus "ox-" plus "-ic," which describes the same parts from a different angle. The key point is that "oxygen" was not known to the ancient Greeks. The element was identified only in the eighteenth century, and the Greek-derived building blocks were assembled by scientists afterward, so the word is a modern coinage made from classical materials rather than something the Greeks used. Its medical sense followed the growing understanding of how the body depends on oxygen.

Synonyms: low-oxygen, anoxic
