Punctuation is the use of special symbols that are added to writing to separate phrases, to show that something is a quotation or a question, etc. They show how the written language is structured and organized. These symbols are also called “marks” and they include among others: brackets ( ), question marks ?, hyphens - , semicolons ; , etc. Some of these symbols are used to end a sentence - end marks, also called end stops - and they show the end of a complete thought. They are the period, the question mark and the exclamation mark. The question mark shows the end of a question and the exclamation mark shows strong feeling or surprise.
