Which prefix means 'none'?

Which prefix means 'none'?

• A. Nulli-
• B. Hypo-
• C. Pan-
• D. Brady-

Answer: (A)

Understanding prefixes that express absence helps decode medical terms. The prefix nulli- means none, or absence of something, exactly matching the idea of “none.” That makes it the best fit for meaning “none.” For instance, nulliparous describes someone who has never given birth, and nulligravida refers to someone who has never been pregnant—both show absence through nulli-. In contrast, hypo- means below normal or deficient, pan- means all, and brady- means slow, so they convey different ideas and do not express the concept of none.
