What is characterized by the suffix "-itis"?

The suffix "-itis" is commonly used in medical terminology to indicate inflammation of a specific organ or tissue. When this suffix is added to the root of a word, it signifies that there is an inflammatory condition present. For instance, "arthritis" refers to inflammation of the joints, and "tendonitis" signifies inflammation of a tendon. Thus, the correct answer reflects the association between the suffix "-itis" and the concept of inflammation in medical language. This understanding is fundamental when interpreting or communicating about various medical conditions.
