In both speaking and writing, you are trying to convey a message. Even if you are just telling a story, or writing a fictional novel, you then want to take your audience to this made up place. You need details, but more importantly, you need words that are best suited to your audience. You have to be precise. If it's a younger audience, you wouldn't use complicated words, but if you're talking/writing about the subject of your phd, you're going to use a more technical language.

The treasure island is a small island near the coast of Spanish America that is inhabited by pirates. The novel's setting has a great impact on its action. The most important effect of the novel's setting is "Because the island is separate from civilization, the characters act in uncivil and lawless ways there."
