Dupin, that's not the Wiki's rule, it's actually a rule of the English language. You can look it up if you want, but it's true. The language that is English contains this rule, not just this wiki. That's just how it is. I'm too lazy to supply a source right now but this is the Internet, you should be able to find a page about it quite easily.
