Root Explanation

Macromolecule → It is formed from "macro-" (from Greek "makros", meaning large) and "molecule" (from Latin "molecula", meaning a small mass or particle). The word "macromolecule" refers to a large molecule, typically composed of many smaller subunits or molecules.

Memory Tip

Think of 'macro-' meaning large, and 'molecule' referring to a small particle — together they describe a large particle made up of many smaller ones.
