The prefix meaning Before is?

• A. Supra-
• B. Para-
• C. Pan-
• D. Post-

Answer: (C)

The idea being tested is recognizing the prefix that means “before.” In medical terminology, before is typically shown by ante- or pre-, as in antepartum (before birth) or prenatal (before birth) or preoperative (before surgery). The options given do not convey that meaning: supra- means above, para- can mean beside or near (and sometimes abnormal in medical terms), pan- means all, and post- means after. So none of the listed prefixes correctly means “before”; ante- or pre- would be the appropriate ones to express that idea.
