So, we know that the one thing we can count on as a constant across all [living] languages is change, right?
That means English, too. Turns out that we're getting a new preposition as recognised by the boffins, but born and bred on our own internets - even right here on the odeck. That's right: "because 'x.'" is now codified as a "prepositional because." This elevates the word from a lowly subordinating conjunction to something grander. Because language.
