What does the suffix -rrhage refer to?

The suffix -rrhage specifically refers to an abnormal or excessive flow or discharge from a body part, particularly related to blood. It is most commonly associated with terms such as "hemorrhage," where "hem/o" refers to blood and "-rrhage" signifies the action of bursting forth or excessive flow of blood. This suffix indicates not just any discharge, but an abnormal one, often implying a pathological condition that requires medical attention. For instance, "menorrhagia" refers to excessive menstrual bleeding, highlighting the suffix's association with abnormal discharge in a medical context.

In the context of the other choices, irregularity does not capture the meaning of the suffix, clotting refers to a different physiological process, and while blood is related to the suffix, it does not encompass the full meaning of an excessive discharge. Thus, the understanding of -rrhage is best encapsulated in its association with abnormal discharge, especially in terms of fluid or blood flow.
