Can I copy and paste something from the thesaurus into my story?

While it is your story and you can do as you like, our thesaurus collections are not meant to be copied and pasted. Readers want to read a story that will bring their imaginations to life, and that will only happen when the story is written in your style, using the best words possible for the story. Personalize the details further by choosing ones that your point-of-view character would use; this will create a more realistic experience for readers, making them feel part of the scene. Good luck!
