Etymology: "Myelogenous" is a technical adjective built from two Greek-derived parts. The first, "myelo-", comes from Greek "myelos", meaning marrow, and appears in medical terms relating to bone marrow or the spinal cord. The second, "-genous", comes from Greek "-genēs" and "-genes", meaning produced by or originating from, the same element found in words like "carcinogenous" and "hydrogenous". Put together, the term describes something that arises from or in bone marrow. It is a modern coinage rather than an ancient word. Ancient Greek writers had "myelos" but never combined it with "-genēs" to name a condition, so the compound reflects the scientific vocabulary of later centuries, when physicians built precise terms from classical roots to describe newly understood tissues and diseases.
