In literature, what is the primary focus of a metaphor?

The primary focus of a metaphor is to suggest a similarity between two different things, illustrating how they are alike in some meaningful way. This figurative language device allows writers to create vivid imagery and convey complex ideas more effectively by comparing the unfamiliar to the familiar. By doing so, metaphors can enhance the emotional impact of a piece, encouraging readers to think more deeply about the relationships and ideas being expressed.

For example, saying "time is a thief" does not mean time literally steals, but it draws a parallel that evokes the feeling of lost moments as if they have been taken away. This creative comparison engages the reader's imagination and provides deeper insight into themes or emotions. Thus, the emphasis on suggesting similarity is what makes metaphors so powerful and prevalent in literature.
