What characterizes a metaphor?

A metaphor is characterized by making a comparison between two unlike things without employing the words "like" or "as." This form of figurative language suggests that one thing is another, thereby adding deeper meaning or understanding to the subject. For example, saying "Time is a thief" directly conveys that time can take away moments from our lives, similar to how a thief might take possessions, without using comparative words.

The options that describe the other choices are not applicable to what constitutes a metaphor. The use of "like" or "as" characterizes similes, exaggeration refers to hyperbole, and stating facts directly does not align with the figurative nature of metaphors. Understanding that a metaphor implies different characteristics enriches the appreciation of language and how ideas can be expressed in nuanced ways.
