The prefix intra- denotes which meaning?

The prefix intra- denotes which meaning?

• A. Within
• B. Between
• C. Across
• D. Beyond

Answer: (A)

The meaning tested is the sense of the prefix intra-. It denotes inside or within, used to indicate something occurring inside a part of the body or an internal space. That’s why within is the best answer. For example, intramuscular means inside the muscle, intracranial means inside the skull, and intranet refers to a network inside an organization. The other ideas describe different relationships: between (inter-), across (trans-), or beyond (ultra- or supra-), so they don’t fit the meaning of intra-.
