A document's primary text is text in the form of sentences or paragraphs, as opposed to captions, titles, lists, and so on. However, some texts are composed of one continuous flow of thought, without breaks between ideas. For example, a newspaper article or blog post consists of a single continuous string of words, but these are separated into different sentences to make reading them easier. Such a string of words is called a running text because the reader can follow its progress from start to finish without needing to stop to think about what word comes next. Running texts are common in newspapers and magazines, but they also appear in books, film scripts, and other forms of writing. They're useful when you want the reader to understand an idea even if they don't read every word of the text. For example, if you are writing an article for a magazine that has a focus on teaching people about food, you wouldn't want to use big words that only certain readers would understand. By using a running text, you can convey the same information to everyone who reads the piece! There are two types of running texts: continuous and interspersed. With a continuous running text, the writer uses punctuation to indicate where one sentence ends and the next begins.
