Similes and metaphors are both types of commonly used figurative language. They both compare two different things in English language and writing. The simile is written using either the word "like" or "as"--"The dog was as black as coal." A metaphor does the same thing without using the words "like" or "as"--"The dog was a siren, barking into the night."
