Etymology: Adenomyosis is a modern medical coinage built from three Greek-derived combining forms. "Adeno-" comes from Greek "adēn," meaning gland, "myo-" comes from Greek "mys," meaning muscle, and "-osis" is the suffix used in medicine for an abnormal or diseased condition. Put together, the name describes a gland-like tissue growing into muscle, which is exactly what happens when the lining of the uterus (endometrial tissue, which is glandular) invades the uterine wall. The word therefore belongs to the same family of clinical terms as "tonsillitis" or "neurosis," assembled from classical roots to name a condition that ancient physicians could not have identified in this form. Its parts are transparent to anyone who knows the Greek building blocks, and that transparency is part of why it was named the way it was: the name is a description of the disease rather than a label inherited from earlier medicine.
