NOAM Chomsky’s wife says reports that the famed linguist and activist has died are untrue.

On Tuesday night, a social media post claiming the celebrated thinker had passed away quickly went viral with many paying their tributes.

But Valeria Wasserman Chomsky told The Associated Press the claims were false after reports of his death circulated on social media early on Tuesday.

“No, it is false,” she wrote in an email.

Chomsky, 95, had been admitted to hospital in Brazil, where the couple resides, while recovering from a stroke suffered a year ago, Chomsky's wife told the AP last week.

But the Beneficencia Portuguesa hospital in Sao Paulo said in a statement that Chomsky was discharged on Tuesday to continue his treatment at home.

Both Jacobin and The New Statesman published obituaries for Chomsky, though the former has since changed its headline from “We Remember Noam Chomsky” to “Let’s Celebrate Noam Chomsky”.

The New Statesman took its essay by former Greek finance minister Yanis Varoufakis down altogether.

The Chomskys have had a residence in Brazil since 2015.

Noam Chomsky, known to millions for his criticisms of US foreign policy, taught for decades at the Massachusetts Institute of Technology.

In 2017, he joined the College of Social & Behavioural Sciences at the University of Arizona in Tucson.
