Etymology: The plural "moduli" is the Latin form of "modulus," a word that began as a small measure of size. Latin "modulus" meant a standard measure or a small measure, derived from "modus," meaning measure, manner or limit. English took the word directly from Latin in the learned tradition of scholars, so it kept its Latin plural ending, which is why mathematicians still write "moduli" rather than "moduluses." The same root produced "module" and "mold." These are doublets, words that came into English by different routes from one source. "Mold," the shape that gives form to something, arrived through Old French and kept the everyday sense of a pattern, while "module" came back through French as a scholarly term for a standard unit of measure. The modulus, a fixed quantity used to measure or scale, is the mathematical descendant of that old idea of a measured unit.

Synonyms: parameters, measures
