In most of the world’s languages, a number of basic words have similar sound structure. A word for ‘nose’ typically has a nasal sound, an /n/ or /m/, words for ‘mother’ an /m/ or /n/, and various bone words, such as ‘knee’ a /k/. It is a mystery how these connections emerge and why they are maintained as languages evovolve over generations of speakers. Are we born to pronounce words in a specific way? Or does every new generation of speakers reinvent similar-sounding words for ‘mother’, ‘father’, ‘knee’, ‘blow’, and so forth? A new study form in Lund (in collaboration with Tübingen) finds that these sound-meaning mappings are more stable than average as words evolve over time. This tendency is strongest for those sounds which are acquired earlier when a child learns a language. Our results indicate that across languages, new generations uphold these sound-symbolic associations and therefore keep pronouncing basic concepts similarly.
