Which prefix is used to indicate name-related terms?

• A. Nomen
• B. Nomin
• C. Noct
• D. Ocul

Answer: (A)

Naming in medical terms is signaled by the prefix that comes from Latin nomen, meaning name. This form appears in words tied to how things are named, such as nomenclature and binomial nomenclature, making it the direct indicator of name-related terms. The other options point to different ideas—noct means night, ocul means eye—so they don’t convey naming concepts. Nomin- is related to name as well, but nomen- is the clearest and most established prefix for naming terminology.
