Etymology: Myelosis is a medical coinage built from Greek roots, not a word from ancient medicine. The first element comes from Greek "myelos," meaning marrow, and the second is the suffix "-osis," used in Greek and Latin-derived medical terms for an abnormal or diseased condition, often one that is progressive or characterized by an increase in something. Put together, the word names a disorder of the bone marrow, the soft tissue inside bones where blood cells are made. The "myel-" element appears in a whole family of modern medical terms, such as "myeloma" and "myelitis" (inflammation of the spinal cord, where "myelo-" refers to the spinal marrow instead of bone marrow). That shared root is why these words look so alike even though they describe quite different conditions. Because the root is Greek and the suffix is a standard medical pattern, "myelosis" was formed by physicians using classical building blocks, rather than inherited through the ordinary history of English vocabulary.

Synonyms: bone marrow disease, myeloproliferative disorder
