What is the most spoken language in the world?

Mandarin Chinese is the most spoken language in the world primarily due to China's large population, which exceeds 1.4 billion people. The language boasts over a billion native speakers, making it the dominant language in terms of number of speakers. Additionally, Mandarin is not only the official language of China but also has millions of speakers in various communities around the globe due to migration and the growing influence of Chinese culture and economy. This widespread use among such a vast population solidifies its position as the most spoken language, surpassing other prominent languages like English, Spanish, and Hindi by a significant margin.
