Trimerize

Part of speech: verb

Definitions

1. Joining three identical molecules together to form a single larger molecule through a chemical reaction
2. Causing three monomer units to link and form one trimer in a chemical process
3. Combining three smaller molecular units into a single compound, typically through catalysis or heat

Etymology: The word is built from "trimer" plus the suffix "-ize". A trimer is a molecule or compound formed from three identical units joined together, and the "tri-" in it points to that threefold structure. The suffix carries a longer history: it comes from an ancient Greek verb ending "-ízein", which turned verbs into the sense of making or becoming something, and that ending passed through Late Latin "-izāre" and Middle French "-iser" before reaching English as "-ize" in Middle English "-isen" forms. So "trimerize" means to convert a substance into a trimer, that is, to join three smaller molecules into one larger one. Chemists needed a verb for this process, and attaching the familiar suffix to the noun "trimer" gave them one in the usual English pattern.
