What suffix indicates a "condition of" in medical terminology?

The suffix that indicates a "condition of" in medical terminology is -osis. This suffix is commonly used to describe a pathological condition or a process, often implying an abnormal state or increase in a specific type of substance. For example, "neurosis" refers to a condition affecting the nervous system.

Understanding this suffix contextually helps in deciphering various medical terms that utilize it. In contrast, the suffix -dynia refers specifically to pain, -cele typically indicates a hernia or swelling, and -atresia describes an absence or closure of a normal bodily opening, none of which denote a general condition as broadly as -osis does.
