This is commonly seen in terms such as "diarrhea," which describes a condition involving frequent discharges of fluid stools, and "rhinorrhea," which refers to a discharge of mucus from the nose, often associated with conditions like a cold or allergies.

Understanding this suffix is crucial in interpreting various medical conditions and their descriptions accurately, as many medical terms related to bodily functions involve this suffix to indicate that a certain fluid is being expelled or released.
