What suffix indicates a condition of abnormal discharge?

The suffix that indicates a condition of abnormal discharge is indeed -orrhea. This suffix originates from the Greek word "rhea," which means flow or discharge. It is commonly used in various medical terms to describe conditions characterized by an excessive or abnormal amount of fluid discharge from an organ or tissue. For instance, "diarrhea" refers to an abnormal discharge of watery stool, while "rhinorrhea" refers to a runny nose.

In contrast, the other suffixes do not pertain specifically to abnormal discharge. The suffix -rrhagia often refers to excessive bleeding or hemorrhage, so it denotes a different type of abnormal condition. The suffix -rrhexis refers to the rupture or breaking of a structure, which also does not relate to discharge. Lastly, -sclerosis is used to indicate hardening of tissues or organs, a condition related to structural change rather than discharge. Thus, -orrhea is correctly identified as the suffix that signifies a condition involving abnormal discharge.
