The prefix Strept- is most accurately defined as which of the following?

• A. Twist
• B. Bend
• C. Strept-
• D. Turn

Answer: (C)

Strept- comes from a Greek word meaning twisted or curved, and it’s used in medical terms to signal a twisted, bent, or braided arrangement—such as a streptococcal chain. When a question asks for the prefix’s definition, the key point is recognizing the actual linguistic element being tested. The best choice is the option that shows the prefix itself, since the task is to identify the prefix, not to translate it into an English word. The other options describe the concept in English (twist, bend, turn) but they aren’t the linguistic unit being asked about. Remember that in terms like streptococcus, strepto- indicates a twisted chain, which helps you infer meaning across related terms.
