Scientists discovered a universal link between the sound of a rolled 'r' and jagged lines, a surprising connection in language.
People from 28 different countries consistently matched the trilled 'r' with a jagged line, showing a powerful sound symbolism.
This finding is even stronger than the famous bouba/kiki effect, suggesting sounds carry more meaning than we thought.
This research reveals that sounds aren't just random; they have an influence on how words for textures and shapes develop in different languages.
