Which root means foot?

Which root means foot?

• A. Pnea
• B. Polikil(o)
• C. Pod(o)
• D. Plant(o)

Answer: (C)

Pod/o- comes from Greek for foot and is the form used in medical terms about feet, such as podiatry and podiatrist. That direct meaning makes it the correct choice for “foot.” The other roots don’t convey foot in standard medical vocabulary: pnea means breath, and polikil(o) isn’t a common root for foot; plant(o) relates to plants or, in some contexts, to the sole of the foot (plantar) rather than the general term for foot itself.
