Which suffix means inflammation of?

• A. -oma
• B. -algia
• C. -itis
• D. -plasia

Answer: (C)

In medical terminology, the suffix that indicates inflammation is -itis. When you see terms like gastritis, dermatitis, or nephritis, -itis signals that the organ or tissue is inflamed. The other suffixes have different meanings: -oma refers to a tumor or mass (like melanoma), -algia means pain (such as neuralgia), and -plasia refers to formation or development, often abnormal growth (like hyperplasia). So -itis is the best answer because it directly denotes inflammation.
