Remember that figurative language are figures of speech that readers used to convey a message in a story. Some of these languages contain similes, metaphors, personifications, hyperbole, etc... In this case, you would use "metaphors and similes to convey the message of a theme in a story, that's because metaphors are things that compare each other without using like or as, and similes compare two things using the words like or as." For example, "always fly like a bird" is a simile while giving you the main idea to go for your dreams because you can't actually fly like a bird and you use figurative language to find out the main idea or theme.

Imagery can make something abstract, like an emotion or theory, seem more concrete and tangible to the reader. By using imagery, writers can evoke the feeling they want to talk about in their readers...and by making their readers feel, writers can also help readers connect to the messages in their work.
