Semi- denotes which meaning?

Semi- denotes which meaning?

• A. Half
• B. In front of, before
• C. Nerve (Nervous System)
• D. Shaped like a top

Answer: (A)

Semi- indicates half or partial. It shows that something is only partly true or in a half form, which is why this meaning fits the prefix. For example, semicircle is half a circle, semiconscious means partly conscious, and semipermeable allows only partial passage. The other options point to different roots or prefixes—“in front of, before” would be ante- or pre-, “nerve” relates to neur- or nerv-, and a shape like a top would be described differently (not with semi-).
