What is the meaning of the suffix "-itis"?

The suffix "-itis" is commonly used in medical terminology to indicate inflammation. When attached to a root word, it specifies the area of the body that is experiencing an inflammatory condition. For instance, "arthritis" refers to inflammation of the joints, and "gastritis" refers to inflammation of the stomach lining. This suffix is fundamental in identifying various diseases and conditions that involve inflammation, which is a key component of the body's immune response.

The other options do not accurately reflect the meaning of "-itis." The term for tumor generally ends with "-oma," while pain often uses suffixes like "-algia" or "-dynia." Surgical removal is typically denoted by the suffix "-ectomy." Understanding these distinctions is essential for interpreting medical vocabulary correctly.
