Here's why:
* Metaphor: A metaphor is a figure of speech that makes a comparison between two unlike things without using words like "like" or "as."
* In the line: The "rotten orange" is being compared to Hero, who has been falsely accused of infidelity and is considered "damaged" by society.
* Meaning: Don Pedro is advising Leonato not to cast Hero aside just because she has been slandered. He is saying that Hero, like a rotten orange, may appear bad on the surface but is still valuable and worth keeping.
This metaphor effectively conveys the message that appearances can be deceiving and that true value lies deeper than surface judgments.
