What makes huh a word—and not, alternatively, the equivalent of a yelp? A laugh, cry or growl, however meaningful, isn’t considered language; even a dog communicates sadness with a whimper. A true word is learned, and follows certain linguistic rules, depending on the language spoken. Huh? fits this definition: For one thing, huh has no counterpart in the animal kingdom; for another, unlike innate vocalizations, children don’t use it until they start speaking. Moreover, in Russian, which doesn’t have an “h” sound, huh? sounds more like ah? In languages using a falling intonation for questions, like Icelandic, huh? also falls. All in all, Dingemanse concludes that huh? is a bona fide word with a specific purpose “crucial to our everyday language.”
