A new study reveals a near-universal association between the trilled R sound and rough textures or jagged shapes, while the L sound aligns with smooth textures or straight lines. Researchers tested over 1,000 participants speaking 28 languages and found that 94% matched the trilled R to jagged lines and 84% matched L to smooth lines, even among speakers of languages without a trilled R.
