I'd always wondered how we ended up with the ampersand sign. I wondered who decided that squigly represented "and", and how it got to be used widespread.
Really. It's just a random squiggly.
And then I discovered the truth. All on my own! A later Google search confirmed, but I was pretty proud that I figured it out before Google searching!
One day while playing with fonts for my business writing class assignment I saw a font with a different ampersand sign than normal.
I took 3 semesters of Latin at the University of Arizona. In latin, the word for "and" is "et". Do you see the E and the T in there?! That was it. Suddenly I realized our modern ampersand was just a morphed cursive form of "et"!
I'm a nerd, but this made me super excited and I shared it with my Latin class the next day. I think maybe only one other kid acted interested. But that didn't dampen the excitement of what I'd discovered.
So if you need a piece of random trivia to give out at the dinner table, this will do it!
