Pro- prefix denotes what meaning?

• A. In front of, before
• B. About, around
• C. Move
• D. Hand

Answer: (A)

Pro- is a prefix that signals something that comes before or is in front of something, or moves forward in time or position. In medical terms, you’ll see pro- in words like prognosis, where it conveys foreknowledge of what may happen before it actually does. That going-before sense is why “in front of, before” is the best match. The other meanings don’t align with pro-: around or about would come from different prefixes (like circu- or peri-), moving isn’t the sense of this prefix, and “hand” comes from manu- or cheir- roots, not pro-.
