Imagery and Figurative Language

At first, I thought imagery was something to do with imagening stuff and I was right., but I learned that this was wrong . I also learned about figurative language. I used to think figurative language was something wierd, but I learned that figurative language is
speech or writing that departs from literal meaning in order to achieve a special effect or meaning, speech or writing employing figures of speech. The three main types of figurative language are Simile, Idiom, and Metaphor is I also learned about figurative language.
