The combining form megal(o) means which of the following?

• A. Small
• B. Enlargement
• C. Large
• D. Black color

Answer: (C)

Megal(o) signals something of large size. It comes from the Greek megas meaning large or great, and it’s used in medical terms to indicate a word root that denotes a large or enlarged form. For example, megalo- appears in terms describing large structures, while the suffix -megaly specifically names enlargement of an organ or part (cardiomegaly = enlarged heart). So the combining form megal(o) means large, not small or a color.
