Quadri- means four?

Quadri- means four?

• A. Two
• B. Three
• C. Four
• D. Five

Answer: (C)

Quadri- is a prefix used in medical terms to mean four. It appears in words like quadriceps, which refers to four muscles on the front of the thigh, or quadrant, which is one of four sections of a circle. Because quadri- denotes four, the correct understanding is four. The other numbers use different prefixes: two is duo- or bi-, three is tri-, and five is pent- or quint-, so they don’t match quadri-.
