τάχειον. [1 verse](adv) "Quickly" is from tachion, a form of the adverb, tacheos, which means "quickly," and "speedily." It actually looks more like the adjective, tacheon, meaning "swift" and "fleet." This is the only time Jesus uses this word. Normally, another Greek word, tachy, which is also an adjective form, is translated as the adverb, "quickly."
