What is a metaphor?

A metaphor is defined as a figure of speech that makes a direct comparison between two unlike things by stating that one thing is another, thus highlighting similarities between the two. For example, saying "Time is a thief" suggests that time takes away life's moments stealthily and effectively, similar to how a thief would steal valuables. This approach allows for deeper meaning and insight into the subject being discussed without using explicit comparative words such as "like" or "as."

The essence of a metaphor lies in its ability to create vivid imagery and provoke thought, enhancing the reader's or listener's understanding of the concepts being conveyed. This direct linkage between disparate ideas can evoke emotions and create connections that enrich the language and discourse.
