Which morpheme means 'pain'?

Which morpheme means 'pain'?

• A. Mast-
• B. -dyn-
• C. -ptosis
• D. Supra-

Answer: (B)

Pain is shown by the combining form -dyn-, which signals a painful condition in medical terms. That meaning shows up in terms describing pain in a body part, so this morpheme directly matches what the question is asking for. In contrast, mast- refers to the breast, -ptosis means a drooping or prolapse, and supra- means above. So -dyn- is the best choice because it specifically denotes pain. You might see examples like gastrodynia for stomach pain or neurodynia for nerve pain, illustrating how this morpheme conveys the sensation of pain.
