The prefix meaning Before; in behalf of is?

• A. Supra-
• B. Post-
• C. Hypo-
• D. Ante-

Answer: (D)

Ante- is the prefix meaning before. It signals something occurring earlier in time or in front of something, as in antepartum (before birth) or anterior (front). The phrase “in behalf of” isn’t a prefix meaning; in medical terms you’d encounter other prefixes like pro- to convey “for” or “in favor of,” but that’s a different usage. The other options point to different directions: supra- means above, post- means after, and hypo- means below. So ante- is the correct prefix for “before.”
