For more than sixty years, Charles Hockett’s ‘design features’ have been widely used as a framework for defining what distinguishes human language from other forms of communication. These features were long treated as a checklist of properties that set language apart.

However, a new study published in Trends in Cognitive Sciences argues that this traditional view is no longer sufficient. The researchers contend that language cannot be captured by a fixed inventory of traits, but is better understood as a flexible system shaped by social interaction, situational context, and human creativity.

In a new reassessment of Hockett’s classic “design features” of language—ideas such as arbitrariness, duality of patterning, and displacement—an international team of linguists and cognitive scientists argues that current research requires a fundamental rethink of what language is and how it evolved.

Their central claim is clear: language is not merely a spoken code. Instead, it is a dynamic, multimodal, socially grounded system shaped through interaction, culture, and shared meaning.

Thanks! It's really interesting to read another background and approach than my own cultural biased one!

Because this article makes it sound as if Hockett is worldwide standard - but at least in my linguistic studies which are now more than a decade ago he was only a "oh btw this exists as well" side note. Together with Bühler/von Thun and even Wittgensteins philosophical approaches the foundation was "there is no one size fits all in linguistic as it's a highly contextual science".

PS: I want briefly over the 2022 study they referred and that showed the same tendency: this is about english linguistics, not generic one. Something they should have added in the title or first paragraph in my opinion as it's not an easy distinction for lay people.

Language is a emergent system. Yes, the various grammar mechanisms are full of patterns and highly logical and usually make up entire systems, but language standardisation and reform is a relatively new concept.

Calling these things "design features" is misleading. Just because evolution took the course of all land mammals having 2-6 legs doesn't mean "design".

Neither are the patterns on a leopard "designed".
