A metaphor is a figure of speech where a word or phrase is applied to an object or action to which it is not literally applicable. It creates an implicit comparison between two things without using words like "like" or "as."
For example:
* "The city was a jungle." Here, the city is being compared to a jungle, implying that it's dangerous, wild, and full of hidden dangers.
