The story of the word

The word only makes sense backwards. Polymer came first, in Berzelius's chemistry of the 1830s, and monomer was cut from it later to name the single unit the chain is made of. Glucose is a monomer, starch the polymer; styrene is a monomer, and the cup in your hand is the polymer.
