Country names

I dont know if this is weird or not, buit one night I couldnt sleep, and I was thinking about country names, and realized, that almost all country names have either an "i," or an "n."And it wasnt jjust a majority, it was an overwhelming majority. I then realized that i is a vowel, so there would automaticly be a lot of countries with an i in the name. But I thought even the n on its own was weird, because there a still a loit of countires with n. The only faukt in that one though is thats mainly because of common words at the end or beging of words like "north," and "Land." But even so, concerning i and n, if you have a country and want to turn it into a nationality, you eithern add an n or an i a the end. For example, America = American or Israel = Israeli. There are some exceptions to that rule like Japan China and Vietnam, because they become Japanese, Chinese, and Vietnamese, but they ALREADY HAVE AN "N" in the name to begin with. I thought that was kind of interesting and nearly frightening, but I think overall, it was worth it.
