Yes, Greek.

You're correct! The word "polymer" is indeed derived from Greek.

To figure out the origin of a word like "polymer," you can break it down into its parts and analyze each one:

1. "Poly" comes from the Greek word "polus," which means "many" or "much." It is often used as a prefix to indicate multiplicity or abundance.
2. "Mer" comes from the Greek word "meros," which means "part" or "unit." It is commonly used in chemical contexts to refer to a repeating subunit of a larger molecule.

When you combine "poly" and "mer," you get "polymer," which describes a substance made up of many repeating units (monomers) linked together.

In summary, "polymer" originates from the Greek roots "polus" meaning "many" and "meros" meaning "part," reflecting the nature of these substances consisting of numerous repeating units.
