What is it about English that makes it so universal as a language? Is it merely that it is the language adopted by the United States of America as the world outside the country becomes fascinated with the blend of cultures and the benefits that come with that melting pot? Sure, the lack of gendered nouns makes things a little simpler than other languages in some respects, but the English language also likes to break it’s own rules, and if you learn most languages at an early age you probably have a pretty equal chance of grasping others as easily as you would with English.
The extension of this question, I suppose, is whether it will continue to be used in such a way. Will it take over in a way that Esperanto could not? With works to preserve dying languages, would there be a movement to stop English becoming ubiquitous if it looked like it was heading that way?
I have heard it suggested that Mandarin could become similarly widely used, and with the number of Chinese people in China and (spreading) throughout the world, it will probably take on a much wider use than it had once upon a time. However, as to whether it will catch on throughout cultures, I am not so certain. Perhaps if the Europeans of the future are much less lazy than I, many more would learn the language and it could become as integrated as English is.
What I am surprised at, I suppose, is that I haven’t heard much in the way of people talking about the ubiquity of Spanish, a language that is widely used across the South American continent, and in increasing use in the USA itself, the country that, perhaps, has done the most to inspire people around the world to take up English as a second language.
Perhaps one day it will.
