Which suffix denotes a disease condition?

The suffix that denotes a disease condition is commonly understood to encompass various types of ailments, which is why the correct choice is "-pathy." This suffix typically indicates a disorder or disease affecting a specific body part or system, such as in the terms cardiopathy (heart disease) or neuropathy (nerve disease). The use of "-pathy" clearly communicates the underlying association with disease processes.

Other suffixes listed have different specific meanings. For example, "-itis" denotes inflammation and is used to describe conditions like arthritis (inflammation of the joints), while "-rrhea" indicates flow or discharge, as seen in diarrhea (abnormal increase in bowel movement fluid). The suffix "-emia" refers specifically to a blood condition, like anemia (a deficiency of red blood cells). Each of these suffixes serves a particular purpose in medical terminology but does not encompass the broader idea of a disease as "-pathy" does.
