The Origin of Enigmatic Isn't a Mystery

The noun enigma can refer to a puzzle, a riddle, a question mark. It’s no mystery then, that the adjective enigmatic describes what is hard to solve or figure out. An enigmatic person, for example, may be someone with a bit of je ne sais quoi. What’s behind a stranger’s enigmatic smile? Your guess is as good as ours. Does the vocabulary in the short story you’re reading render it a tad enigmatic? Better grab a dictionary! Both enigma and enigmatic come from the Greek verb ainissesthai, meaning “to speak in riddles.”
