I’m writing in English, pero hablo español. The two laguages could be considered «lingua franca» in the western cultures.
I’ve seen this graphic several times, and I’m proud that the Spanish is the world most extended laguage after the Chinese, but… the English is the most influential due to the Internet and the technological advances of the anglo speaking countries. The fact that Spanish is now the de facto second laguage in the United States could change all of this.
The negative of this. There are thousands of laguages that will just disapear in the next few years. Even in sight of the Romantic Historicist strong fighting to save them…..
