Bengali is the sweetest language in the world.

The claim is false and baseless. The United Nations Educational, Scientific and Cultural Organization did not confer any title to the language.

The claim is false and baseless. The United Nations Educational, Scientific and Cultural Organization did not confer any title to the language.A claim stating that the United Nations Educational, Scientific and Cultural Organization(UNESCO) declared Bengali as the sweetest language in the world has been doing rounds on social media since 2010, even with print media reported the same. There was a rumor asserting that UNESCO held an online survey on selecting the world's sweetest language, which ranked Bengali as first, followed by Dutch and French in the second and third place. However, this is false. Neither UNESCO nor any other authorized organization has declared Bengali as the world's sweetest language.

On August 23, 2010, Subir Ghosh, a journalist in his blog named Write2Kill, affirms that he contacted UNESCO to clarify this. He received clarification from Sue Williams, the chief of UNESCO's Bureau of Public Information, asserting that the claim is a hoax.

According to Indian Express, UNESCO declared February 21 as the 'International Mother Language Day' in 1999 to promote "linguistic and cultural diversity and multilingualism." As per the online database, in 2019, the widely spoken language was English with 113 billion in the world, 1.17 billion Mandarin speakers, followed by Hindi in third place with 615 million speakers, while with 265 million speakers, Bengali was in seventh place.
