Pitman Shorthand is like a secret code language that people use to write things down really fast. It's like taking notes, but instead of writing out all the words like we do in school, you only write down the important parts.
Instead of writing out big words like "important," you only write the first letter or sound, kind of like a secret symbol. So instead of writing the whole word "important," you'd just write down "im" with a special symbol.
Also, instead of writing from left to right, like you do in school, you write top to bottom and left to right.
It's like writing in sneaky code, so you can write faster without worrying about spelling everything out. But you have to learn the code first, it's like learning a secret language!
