Here's why:
* Native Speakers: Mandarin Chinese has the most native speakers, with over 900 million people speaking it as their first language.
* Total Speakers: While English has a significant number of speakers, Mandarin Chinese has an even larger number of total speakers when you include those who speak it as a second language.
However, English is considered the most widely spoken language in the world. This means it's the language used in more countries and contexts than any other. It's the official language of many nations, and it's commonly used in business, science, and technology.
So, while Mandarin Chinese is the most used language in terms of speakers, English holds a strong position as the most widely spoken and used globally.
