Linguists Tested 191 Universal Grammar Rules. Only One-Third Survived
26th February 2026
Although the world’s languages differ enormously in sound systems, vocabulary, and structure, researchers have long observed that certain grammatical patterns appear repeatedly across cultures. A new study finds that many of these recurring features may be more than a coincidence.
After applying advanced evolutionary modeling techniques, the researchers report that about one-third of the long-proposed “linguistic universals”—patterns believed to exist across all languages—show clear statistical support.
The international research team, led by Annemarie Verkerk (Saarland University) and Russell D. Gray (Max Planck Institute for Evolutionary Anthropology), analyzed data from Grambank, the most extensive global database of grammatical features. They tested 191 proposed universals across more than 1,700 languages, making this one of the broadest examinations of cross-linguistic structure to date.
