Interesting. I cannot imagine what would have to take place to add a new letter to the American-English alphabet. I cannot even imagine it happening. (I called it the American-English alphabet because the UK-English one doesn’t seem to pay any attention to the fact that the letter Z exists and adds all kinds of U’s where they don’t belong and so on…)
But the Swedish have gone and done just that. They added “W
”. I cannot imagine someone changing the alphabet. Imagine the work that goes on behind that.
