Every word is built from atoms. An atom is one mark with one meaning, like ASSERT ⧑ or QUERY ⧓. Put two or three atoms together and you get a word. A sentence opens with a mark that says what kind of sentence it is (a statement, a question) and closes with ⧗.
Some marks don't change the word. They change the sentence around it: past tense, not, more, most. Names the language has no word for are spelled out in braille.
Reading it back gives you the bones of the sentence in capitals, not the exact original words. Here is one sentence, run through the same translator this site uses:
