While English is one of the most widely spoken languages in the world, it's not the most spoken in terms of native speakers. That title belongs to Mandarin Chinese.
Here's a breakdown:
* Mandarin Chinese: Over 1 billion native speakers.
* English: Over 370 million native speakers.
* Hindi: Over 600 million speakers (including non-native).
So, while English has a large number of speakers overall, including those who speak it as a second language, it is not the language spoken by the most people as their native tongue.
