There are thought to be around 6,500 languages in the world today (that was a free bonus fact), though around 2000 of these languages have less than 1000 speakers. Of the 7.5 billion people on Earth, just over a billion of us speak Mandarin or Cantonese, the languages of Earth’s most populous country, China. But these are just the warm up facts, allow us to really ‘impress’ you with some of the lesser known language facts!
