The combining form poeis means what?

• A. Air, lung
• B. Forming
• C. Foot
• D. Varied

Answer: (B)

The idea here is understanding a Greek-based root that signals making or forming. The element poie- (often seen in poiesis or poietic terms) comes from to make, form, or produce. That’s why it’s used in medical terms to describe processes of formation, like hematopoiesis (blood cell formation) or osteopoiesis (bone formation). So the combining form poeis means forming. The other options point to different concepts: air/lung comes from pneum- or pulmon-, foot from ped- or pod-, and varied from roots like vari- or hetero-, which don’t carry the sense of making or forming.
