Which root means "foot"?

• A. Pneum(o)
• B. Poeis
• C. Pod
• D. Poly

Answer: (C)

The meaning of foot is carried by the root pod-, which comes from the Greek pous for foot. It appears in many terms related to the feet, such as podiatry or podiatrist. That connection to the anatomy of the foot is what makes pod- the correct choice here.

Pneum(o) refers to air or the lungs, poly- means many, and poiesis (or Poeis) relates to making or producing. Those roots point to different concepts, not to the foot, so they don’t fit the meaning in this question.
