Which prefix means difficult or painful?

• A. dys-
• B. mal-
• C. a-/an-
• D. hyper-

Answer: (A)

The main idea is prefixes that signal difficulty or pain in medical terms. The prefix dys- means abnormal, difficult, or painful. It shows up in words like dysfunction (impaired function), dysuria (painful or difficult urination), and dyspepsia (indigestion that can be painful or uncomfortable). That sense of impaired performance or distress is exactly what the question is asking for. The other prefixes don’t carry that same emphasis. Mal- means bad or ill in general, as in malnutrition, which is bad nutrition but not specifically about pain or difficulty of function. A-/an- indicates absence or lack, as in apnea (absence of breathing) or anemia (lack of healthy red blood cells). Hyper- means excessive or above normal, as in hyperglycemia (high blood sugar), which isn’t about pain or difficulty per se. So the prefix that best conveys difficult or painful conditions is dys-.
