The prefix CONTRA- denotes which meaning?

• A. Around
• B. Walk
• C. Against
• D. Down

Answer: (C)

Contra- indicates opposition; when you see this prefix, think against or opposite. In medical terms, contra- is used to signal that something acts against another thing or isn’t appropriate due to a condition. For example, contraception is against conception, a contraindication is a condition that makes a treatment unsuitable, and to contradict is to speak against something. So the meaning conveyed by CONTRA- is “against.” Other directional ideas like around or down come from different prefixes (circum- or peri- for around, de- or hypo- for down), and walk isn’t represented by a standard medical prefix.
