Literary devices are structures used by writers to convey messages and themes in their works. There are two main types: literary elements which are inherent parts of stories like characters and plot, and literary techniques like metaphor and simile which writers employ purposefully. Common literary elements include plot, which is the sequence of events; point of view, which is the perspective; setting, which is the time and place; characters; and theme, which is the central idea. Common literary techniques include imagery, simile, metaphor, personification, irony, and symbolism. These devices help readers to better understand, analyze, and appreciate literary works.
