What is a metaphor?

A metaphor is a figure of speech that directly compares two unlike things by stating that one thing is another, helping to create an imaginative connection between the two. This comparison bypasses the use of "like" or "as," which distinguishes it from a simile. For example, saying "Time is a thief" suggests that time steals moments from our lives, invoking a deeper understanding of how quickly time can pass without making a literal comparison. This allows for richer imagery and can convey emotions and ideas in a more impactful way. Consequently, this definition aligns precisely with the characteristics of a metaphor, making it the most accurate choice.
