What are metaphors?
Metaphors are figures of speech that compare two unlike things. For example, the sentence Alyssa's eyes are sparkling stars is a metaphor because it compares Alyssa's eyes to a star. In addition, the sentence Ryan was a hog at dinner is a metaphor because it compares Ryan to a hog.
Keep in mind, while metaphors and similes both compare unlike things, metaphors do not use the words "like" or "as" in the comparison.
