The prefix meaning beside, beyond is?

• A. Chondr-
• B. Para-
• C. Proct-
• D. Megal-

Answer: (B)

Para- means beside or near a reference point, and can also convey "beyond" in some contexts. That makes it the fit for describing something located beside another structure or extending beyond it, such as paranasal (beside the nasal cavity) or parathyroid (beside the thyroid). In contrast, chondr- refers to cartilage, proct- to the rectum, and meg- to large. So para- is the prefix that captures the meaning "beside, beyond."
