Etymology: Caffeine was first isolated in 1819 by the German chemist Friedlieb Ferdinand Runge, and the name came later, but the word "caffeinated" is a plain built-up form: "caffeine" plus the verb ending "-ate" (as in "caffeinate", to add caffeine to something) plus the "-ed" that turns it into an adjective describing a drink or product that has had caffeine added. The root itself traces back to "café," the French word for coffee, which came into European languages from Turkish "kahve" and Arabic "qahwa." The "-ate" ending is the interesting part for a reader. It comes from Latin "-ātus," the ending used to form adjectives and verbs from nouns, so the word is a chain of familiar pieces stacked together. Nothing about it is a myth or a surprise twist; its meaning has stayed close to its literal sense of "having caffeine added."
