Which of the following suffixes indicates inflammation?

  1. -Phagia

  2. -itis

  3. -pnea

  4. -emia

The correct answer is: -itis

The suffix -itis is derived from the Greek word meaning "inflammation." A suffix is a group of letters placed at the end of a word to form a new word with a different meaning. In the context of medical terminology, the suffix -itis generally refers to inflammation of a specific body part or organ. Therefore, options A, C, and D are incorrect because they do not indicate inflammation. Option A, -Phagia, refers to eating or swallowing. Option C, -pnea, refers to breathing. Option D, -emia, refers to blood. While these suffixes are commonly used in medical terms, they do not indicate inflammation. Therefore, option B, -itis, is the correct answer.
