The prefix neo- denotes which concept?

• A. Night
• B. Name
• C. Old
• D. New

Answer: (D)

Neo- denotes new. This Greek prefix signals that something is newly formed or recently occurring, which you can see in terms like neonatal (relating to a newborn) or neoplasm (a new growth). The other options point to different roots: night comes from noct-, name from onom-, and old from paleo- or archaeo- depending on context. So the concept being tested is recognizing that neo- means new.
