Which suffix indicates a state or condition?

The suffix that indicates a state or condition is -osis. This suffix is commonly used in medical terminology to denote an abnormal or diseased condition. For example, "fibrosis" refers to the condition of having excessive fibrous tissue growth, illustrating how -osis describes a specific state regarding tissue composition.

In contrast, -pathy refers to a disease or disorder, typically indicating a condition affecting a specific organ or system. -itis is used to denote inflammation, which is a specific type of condition rather than a general state. -emia refers to a condition related to the blood; for instance, "anemia" involves a state of having a deficiency of red blood cells but is more specific than the broader concept of -osis.
