Word geekery: the future of the English (American) language.
Predicting the future of the English language is rather easy, in the short term. The odds are, over the next few decades its New World dialects are going to gain increasing global dominance, accelerating the demise of thousands of less fortunate languages but at long last allowing a single advertisement to reach everybody in the world. Then after a century or two of US dominance some other geopolitical grouping will gain the ascendancy, everyone will learn Chechen or Patagonian or whatever it is, and history will continue as usual. Ho hum. But apart from that… what might the language actually look like in a thousand years time?
Down my street, I wouldn’t be surprised if something like this happened within a thousand years.
