Which prefix means 'After'?

Which prefix means 'After'?

• A. Post-
• B. Vert-
• C. Phrag-
• D. Mechano-

Answer: (A)

Post- is a prefix that signals time after something has occurred. In medical terms, it shows that an event happens subsequently—for example, postoperative refers to after surgery, postpartum means after birth, and postmortem means after death. This temporal sense is what makes post- the best fit for “after.” The other prefixes point to different ideas: vert- comes from turn or change in direction (as in vertical or invert), phrag- relates to a barrier or partition (like fence), and mechano- relates to movement or mechanical force (as in mechanoreceptor). They don’t convey timing in sequence, which is why they don’t match the meaning of “after.”
