Root Explanation

Copolymer → It is formed from "co-" (meaning together) and "polymer" (from Greek "polus", meaning many, and "meros", meaning parts). The word describes a substance made from two or more different types of monomers combined together.

Memory Tip

Think of 'together' ('co-') and 'many parts' ('polymer') to remember that a copolymer is made from multiple types of building blocks.
