What does the suffix -osis indicate?

The suffix -osis signifies an abnormal condition, typically representing an increase or disease state related to a specific part of the body or system. This suffix is often used in medical terminology to describe various disorders or conditions, such as "scoliosis" (abnormal curvature of the spine) or "nephrosis" (abnormal condition of the kidneys).

Other options describe different processes or states that do not align with the meaning of -osis. For instance, surgical procedures or operations are denoted by suffixes like -ectomy or -otomy. The prefix or suffix representing the study or science of a particular field typically involves -logy, indicating the academic discipline rather than a pathological state. Lastly, the removal of something is articulated through suffixes like -ectomy. Therefore, recognizing -osis as indicative of an abnormal condition is crucial in interpreting medical terminology accurately.
