I'm Still Confused...

So I heard someone recently try to differentiate a British accent and an English accent. Apparently, people with British accents don't pronounce their "t"s... "So it's like, 'Bri-ish.' Get it?"

*FACEPALM*

I realize it's a difficult concept, but I think that's incorrect.

I also realize that I probably will be corrected once I'm over there, but this is a question that I think I've finally figured out:

"What's the difference between Britain, England, and the UK???"

Okay, here goes.

England is a country. It is surrounded by Scotland and Wales. It lies in about the middle of Great Britain.

Great Britain (or just Britain) is technically the name of the largest island in the UK. So, the majorities of England, Scotland, and Wales are in Britain. However, all three countries have islands off of the mainland, which are not part of Britain.

The UK is more of a political term than geographical. It refers to the "sovereign state" of England, Scotland, Wales, and Northern Ireland.

Not gonna lie, that part confuses me, especially since a sovereign state is sometimes called a country. A country within a country???

... COUNTRY-CEPTION.

Why has that meme not been created yet?? A-la the wonderful Inception puns that are all over the interwebs!

But, I digress.

So, the UK is, for me, the most confusing part. There are a lot of political things that go into the connection, like the House of Commons, and that Prince Charles is the Prince of Wales (though his mother is currently the Queen of England). I definitely have a lot to learn when I'm there! However, as Psyk60 commented on the following video, "there's no particular reason why one country can't contain sub-units that are also called countries. Just like how the USA is itself a State despite being made up of states." Hey, hey!! Now I get it... more than I did. Still lots of confusion.

This is where I learned most of this... prepare for your mind to be blown!
