Which suffix means formation or plastic repair?

• A. ectomy
• B. emia
• C. penia
• D. plasty

Answer: (D)

The key idea is a suffix that signals surgical repair or reconstruction. -plasty means a procedure to repair, reshape, or reconstruct a part. It comes from Greek plastikos, meaning formed or molded, and it shows up in terms like rhinoplasty (nose reshaping), angioplasty (repair/restore function of a blood vessel, often by widening it), and arthroplasty (joint reconstruction). This focuses on repair or reconstruction, not just growth or removal. By contrast, endings like -ectomy denote removal, -emia a blood condition, and -penia a deficiency, which is why -plasty is the best fit for “formation or plastic repair.”
