Would you like to be understood all over the world? A tall order, but researchers at the Max Planck Institute of Psycholinguistics recorded informal conversations and analysed the tapes for words that sounded like ‘Huh?’, discovering that all languages contain a version of it with the same meaning. They describe it as a simple, minimal, quick-to-reproduce questioning syllable, and a word we learn to say rather than a grunt we are born knowing how to make. Huh? However, we rarely use it in our German group conversations! Sylvia Mountford.
