The World’s Most Spoken Language

There are about 6,900 languages spoken in the world. The number of speakers of these languages goes from tiny to very large. One of those languages which have a very large number of speakers is Mandarin Chinese with nearly 1 billion speakers! It’s only one of 297 languages that people speak in China, but it’s by far the biggest. About 70% of the population speak it, compared to the 6.5% that speak the next biggest language, Wu.

Language experts think that it spread to so many people in China because it’s a language from the north of the country. There aren’t as many mountains in the north so it was easier for people to travel and for the language to travel too.

The Chinese government uses Mandarin in most of the country, especially in the capital city, Beijing. In Hong Kong and Macau, however, government officials can also use Cantonese. No other languages are used by the government.

The Mandarin vocabulary is quite large. It has more words than French, for example (370,000 words compared to around 350,000), but fewer than English, which has around 470,000 words.

Many students of Mandarin find the grammar quite easy, but the pronunciation is more of a problem.
