What is the implication of the root word "-osis"?

The root word “-osis” is derived from Greek and is commonly used in medical terminology to denote a condition or process, particularly one that is abnormal or diseased. When attached to a root word, it conveys a sense of a medical condition or a state of being, often related to pathological changes. For example, "fibrosis" refers to a condition characterized by an excess of fibrous connective tissue.

In the context of the other options, while "tumor," "bone," and "shape" may denote specific types or aspects of diseases or anatomical features, they do not capture the broader idea of an abnormal condition which "osis" specifically implies. Therefore, recognizing that "-osis" is used primarily to indicate some form of condition provides clarity on why "condition" is the most appropriate choice. This understanding is crucial for accurately interpreting medical terms, especially in fields related to health, biology, and pathology.
