What does the combining form cyc mean?

• A. Circle
• B. Bladder, sac
• C. Down, from
• D. Tooth

Answer: (A)

The core idea here is recognizing that cyc is a combining form tied to a circular idea. It comes from Greek kuklos, meaning circle, and it’s the same branch you see in terms like cyclic, cycle, or cyclone. That root signals something about shape or recurrence being circular rather than relating to a bladder or sac (which uses cyst-, as in cystic) or to directions like down/from (which would use other prefixes or roots) or to teeth (odont-). So cyc points to circle, making circle the correct interpretation.
