Etymology: Cyanosis is a compound built from two Greek elements. The first, "kyano-", comes from Ancient Greek "kuanos", meaning dark blue, and the same root gives English "cyan," the bright blue-green of printer's ink. The second, "-osis", is a suffix that turns a noun into the name of a condition or abnormal state, so the word literally describes a state of turning blue or dark. The Greek word "kuanos" was itself applied to a range of dark blues and was used for lapis lazuli and the dark enamel of Greek writing, but the medical sense belongs to a later, deliberate coinage. Physicians took the classical elements and built the term in New Latin, the scholarly Latin of early modern science, in order to name the bluish tint that comes from too little oxygen in the blood. The plural "cyanoses" is simply the regular Greek-derived plural of "cyanosis," following the pattern of words such as "diagnosis" and "prognosis," and it refers to several separate instances of the condition.
