The prefix Trip- denotes which concept?

• A. Push
• B. Rub
• C. Grind
• D. Pull

Answer: (B)

This prefix signals a rubbing or friction-based action that reduces a substance. In medical terminology, forms like triturate and trituration come from a root meaning rubbed or ground down, describing the process of rubbing a substance in a mortar and pestle (or by similar grinding) to make a fine powder. That friction-based action is why the concept is “rub.” Push or pull describe directional forces and don’t capture the rubbing/abrasion idea, and while grinding is related, the key notion tied to this prefix is rubbing down or reducing by friction.
