Researchers Confirm Shared Grammatical Features in a Third of the World's Languages

An international team of researchers from Germany has made a significant discovery, confirming the existence of shared grammatical features across a third of all language groups worldwide. This research, published on the Science Daily platform, emphasizes that despite the vast diversity of languages, certain grammatical patterns consistently recur.

The study was led by Annemarie Verkerk from Saarland University and Russell D. Gray from the Max Planck Institute for Evolutionary Anthropology. They analyzed 191 proposed linguistic universals using the Grambank database of grammatical features, which encompasses over 1,700 languages. This allowed the scientists to achieve more accurate results by taking into account the variety of language structures.

The authors of the study note that it is intriguing that languages do not evolve randomly in the face of immense linguistic diversity. Annemarie Verkerk highlighted, "In the context of immense linguistic diversity, it is intriguing that languages do not evolve randomly." This suggests that there are certain patterns that determine the development of languages.

Previously, linguists had attempted to avoid similarities between related or neighboring languages by selecting samples from distant regions. However, this approach may have weakened the results, failing to fully eliminate hidden connections and not demonstrating how languages change over time. Therefore, this time the researchers employed a so-called Bayesian spatial phylogenetic analysis, which considers both common ancestry and geographical influence. This method provides a significantly higher level of statistical accuracy.

As a result of the study, the scientists identified recurring structures that repeatedly emerged in unrelated languages from different parts of the world. In particular, this pertains to preferences regarding word order, such as whether verbs are placed before or after objects, as well as the hierarchical organization of grammatical relationships within sentences. This discovery indicates that there are deeply shared cognitive and communicative forces that reduce languages to a limited set of preferred grammatical solutions.

Verkerk also noted, "I am very pleased that the different types of analyses we conducted converged on very similar results. This suggests that language change should be a central component in explaining universals." This underscores the importance of further research in this field, as understanding shared grammatical features can aid in the development of linguistics and language studies as a whole.

Thus, the research conducted by the international team of scientists opens new horizons for the study of languages and their evolution, confirming that despite diversity, languages possess common traits that can be studied and analyzed.
