The opposite of literal language is figurative language. Figurative language is language that means more than what it says on the surface.
It usually gives us a feeling about its subject. For example, one poet writes about the "song of the truck." She does not mean that a truck can actually sing. Rather, she is speaking figuratively. She is referring to road noises as music. By using the word song, and suggesting music, she brings joyful feelings to mind.
This activity gives students a great way to write and recognize figurative language.
