Prefixes and Word Parts: TEAS Practice Question with Answer & Explanation

Understanding the Prefix "Inter-"

In the TEAS English and Language Usage section, you are expected to identify the meanings of common Greek and Latin prefixes, suffixes, and roots. Understanding these word parts allows you to "decode" medical and technical terminology even if you haven't seen the specific word before.

The correct answer is C: Between or among.

Why Choice C is Correct

The prefix inter- specifically denotes a position or relationship that occurs "between" two or more distinct entities.

• Intercellular: Found between cells.
• Interstate: A highway that goes between states.
• International: Relationships between nations.
• Intermission: A pause between acts of a performance.

Analysis of Incorrect Options

• A: Across or through. This is the definition for the prefix trans-. For example, transcellular (through cells) or transport (to carry across).
• B: Below or under. This is the definition for the prefix sub- or hypo-. For example, subcutaneous (under the skin) or hypodermic.
• D: Against or opposite. This is the definition for the prefix anti- or contra-. For example, antibacterial (against bacteria) or contradict (to speak against).

Nursing Connection: Inter vs. Intra

One of the most common points of confusion for nursing students is the difference between inter- and intra-.

• Inter- means between separate things (e.g., interdisciplinary teams involve different departments working together).
• Intra- means within a single thing (e.g., intravenous means "within the vein").

If you see a question about "intercellular" fluid, it refers to fluid in the spaces between cells. If you see "intracellular," it refers to fluid inside the cell membrane itself.

Memory Tip

Think of an Interstate highway. It is a road that connects one state to another; it travels between them. Conversely, an Intramural sports team is a league where students play against other students within the same school.
