Polymerises

Part of speech: verb

Definitions

1. The process of combining multiple smaller molecules into a larger, more complex structure, known as a polymer
2. The act of chemically linking monomers together to form macromolecules, resulting in substances with distinctive physical properties
3. A transformation that enhances molecular chains, creating materials with varied characteristics through the union of simpler units

Etymology: "Polymerises" is the third-person singular form of "polymerise", the British spelling of "polymerize", meaning to link many small molecules into one large chain or network. The verb is built from "polymer" plus the suffix "-ise", which turns a noun into a verb meaning "to make into or undergo" the thing named. The noun "polymer" came first, formed in the 1860s from Greek "polymeres", meaning "having many parts", from "poly" ("many") and "meros" ("part"). The chemist who used the term, Charles Adolphe Wurtz, applied it to compounds that shared the same composition but had different molecular weights, so the sense was not quite what it is today. The modern meaning of a large molecule built from repeated units emerged later, once chemists understood that such chains were real structures. The verb followed the noun in English, appearing around 1865 when the noun was already in use. Its formation follows the usual pattern for chemical verbs, so it describes the process as much as the product.
