When I was younger (think college), I couldn't spell the word privilege to save my life. For whatever reason, I just couldn't learn the order of the letters. I had to look it up every single time. Finally, one day I decided to learn it, for once and for all, and I did. It was simple, once I actually tried.
There's an epidemic of the privilege situation going on, and it spans the globe. Working at a publishing company, I read a lot of proposals and descriptions of books claiming they were indispensable. But they were actually indispensible. The first few times I thought nothing of it, because I wasn't sure how to spell that word. But then when I saw it written the other (right) way, I figured it was just another American/British English spelling difference. So I looked it up, only to find that -ible doesn't even exist.
Since that revelation, I've come across the word countless times, and there was always a 60/40 split, wrong to right. So now I'm just stumped. Is this all a big conspiracy to get me to think I'm spelling the word correctly but really I'm wrong? Or are entire countries unaware of the word's proper spelling? Honestly I'm not sure which it is.
