Which suffix means run; running?

• A. -asthenia
• B. -drome
• C. -clast
• D. -algia

Answer: (B)

The concept here is recognizing common medical suffixes and what they mean. The suffix that means run or running is -drome. It comes from a Greek root meaning running or a running together, which is why it’s used in terms like syndrome—literally a set of signs that run together. That idea of things “running together” aligns with how -drome signals a running or flowing together of symptoms.

The other suffixes signify different ideas: -asthenia means weakness, -clast means to break or a breaking instrument, and -algia means pain. So the suffix that best matches “run; running” is -drome.
