In what way does a metaphor differ from a simile?

A metaphor differs from a simile primarily in that it establishes a direct identity between two unlike things without using the words "like" or "as." This characteristic allows metaphors to create a more profound and often more implicit comparison, suggesting that one thing embodies another, thus inviting readers to find deeper meaning in the relationship. For instance, saying "time is a thief" implies that time steals moments from our lives, which is a more powerful assertion than simply saying "time is like a thief," as a simile would.

The fact that metaphors suggest an identity—not just a comparison—allows them to convey complex ideas or emotions more succinctly. This creates vivid imagery and promotes imaginative engagement, which enriches the reader's understanding and experience.
