You have no fucking clue what it used to be like. It was an illegible mess of a language back 200 years ago. Around the time of the colonies, we had to build on what we had and teach kids what we only perceived as common terms rather than a slur of slang-like words. I know this because I got a early 19th century children's school book that was passed down from my mum's side, and it is the biggest spelling and grammar mess I have ever seen. I mean, we didn't have some huge library or university right there, we had to build that shit ourselves, use whatever books we may have brought over from jolly old England or write them ourselves with our screwed-up, compiled understanding of english. And, things got even worse when immigration took off. Being a "melting pot", we have so many different cultures mixing together into one nation that it's nearly impossible to keep everything straight while having a huge influence from many different countries impact our way of life. Trust me, it wasn't easy, but we've done the best we can.
