English Has a New Preposition, Because Internet
What's fascinating to me is that, unlike so many other language "changes", this isn't caused by laziness or carelessness.  This seems to be a rare case where removing words adds information, rather than removing it: "The talks failed because of politics" means roughly what it says, while "The talks failed because politics" means roughly "The talks failed because of politics, which is the kind of thing that always happens when politics are involved".Any linguists care to comment whether there's a term for this kind of meaning compression? "Idiom" doesn't quite seem to cover it.
