Early Greeks had hardly any punctuation and even changed the direction of their writing. They changed to a way of writing that favored right handed people and showed where a new paragraph began by underlining the first line of it. Later the Greek playwright , Aristophanes, invented mark to show where the readers should take a breath. the Romans made writing much easier to read by putting dots between words and by moving the first letter of a paragraph into the Greek marks such as the colon mark to indicate phrase endings. In he middle ages this system of punctuation broke down because every few people could read and write but writers kept a space at the end of a sentence and continued to mark paragraphs. Eventually words were separated again and new sentences began with a larger letter.
