Which prefix means large in the term megacolon?

Explanation:
Understanding size prefixes helps you see what a medical term is saying about a condition. In megacolon, the part that indicates “large” is mega-. This prefix is attached to the root colon to convey an enlarged colon. While macro- also means large and megalo- is another form meaning large, they appear in different words (macro- in terms like macrocyte or macroeconomics; megalo- in terms like megalocephaly). Micro- means small, which doesn’t fit this term. So megacolon literally means a colon that is enlarged.
