Papua New Guinea speaks more languages than any country on Earth

With over 7,000 living languages spoken worldwide, you might expect them spread evenly across crowded nations. Instead, the single most linguistically diverse country is Papua New Guinea, where roughly 840 languages are spoken — more than 10% of all the languages on the planet.

These are not dialects of one tongue but distinct languages, many mutually unintelligible and belonging to entirely separate families. Rugged mountains, dense rainforest and deep valleys long kept communities isolated, and small groups developed and held onto their own speech over thousands of years.

One country with about 10 million people carries more than a tenth of humanity’s linguistic heritage.

To bridge the gap, Papua New Guineans rely on shared lingua francas such as Tok Pisin and Hiri Motu alongside English. The country is a living reminder that geography, not population size, is often what multiplies languages.
