Explain what a 'literary device' is.

A literary device refers to the various techniques that authors use to convey deeper meanings, create particular effects, or enhance the overall narrative of their work. These devices include figurative language such as metaphors and similes, structural components like foreshadowing and flashbacks, and elements that contribute to the thematic depth of a piece, such as symbolism and imagery. By employing these techniques, authors can evoke emotions, illustrate concepts, or draw readers into the story more effectively. Understanding literary devices is crucial for analyzing and appreciating the layers of meaning within a text.
