What's the most universal utterance in languages across the globe? Huh? Correct! Huh? That's right. Huh? Exactly. Because a new study finds that everybody around the world does indeed say "huh?" The finding is the journal PLOS One. The researchers were exploring linguistic tools people use to assure fluid communication. In this case, they were looking for an interjection that signals that a listener missed something, and prompts the speaker to repeat or rephrase the original statement. In other words, something that works like the English word "huh?" So they eavesdropped on nearly 200 conversations in 10 different tongues, from Italian to Icelandic. And they found that, in language after language, a word that sounds a lot like "huh?" gets the job done. For example. It's short and sweet so it's likely to stop the speaker before the listener gets too lost. And it sounds like a question, so it warrants a response.
