Which suffix means breathing?

Which suffix means breathing?

• A. -cardia
• B. -pnea
• C. -cide
• D. -lysis

Answer: (B)

Breathing terms are built with the suffix -pnea, coming from the Greek word for breath. This suffix signals respiration, as seen in words like apnea (no breath), dyspnea (difficult breathing), eupnea (normal breathing), and hyperpnea (increased breathing). That makes -pnea the suffix related to breathing. Other suffixes here have different meanings: -cardia refers to the heart, -cide means to kill, and -lysis means to break down. Recognizing -pnea helps you identify terms about respiration quickly, which is important for assessing a patient’s breathing status.
