Did you know?

Despite meaning “abundance,” the Latin word copia has not led to an abundance of words in English; in other words, its descendants are far from copious—at least on the surface. There’s copious, of course, which comes from copia by way of Middle English and has been used since the 14th century, when it first described things—such as farmlands or ore deposits—that produce abundant yields. Then there’s cornucopia, which combines this same root with cornu, meaning “horn,” and refers to an inexhaustible store or abundance of something (as well as to a decorative horn or horn-shaped basket overflowing with produce and used as a symbol of abundance). Finally, there’s the commonplace word copy, used as both noun and verb. That’s all she wrote… unless you consider the mucho copious amount—nay, cornucopia—of words that start or end with copy, from copycat to photocopy to copypasta.
