Etymology: "Parameterization" is a straightforward formation: it combines "parameter" with the suffix "-ization," so the real story lies in the parts. "Parameter" was coined in the 17th century from Greek roots meaning "measure beside" (from "para," beside, and "metron," measure), originally a term for a fixed quantity in a mathematical expression. The suffix "-ization" is a chain of borrowings: Ancient Greek "-izein" passed into Late Latin as "-izare," then into Old French as "-iser," and reached Middle English as "-isen," which became the English "-ize." Attached to "-ation," which came into English through Old French from Latin "-ātiō," it forms nouns denoting the process of making something a particular kind of thing. Put together, "parameterization" names the act of expressing something in terms of parameters, meaning that a system or problem is described by adjustable variables rather than fixed values. The word is a modern technical coinage built from these established pieces, not an ancient term.
