The phrase "The moon rocks in the stormy cloud" is an example of a metaphor.
Here's why:
1. Metaphor: A metaphor is a figure of speech that compares two different things by stating one thing is another. In this case, comparing the moon to a rocking motion within a stormy cloud is a metaphorical expression.
2. Analysis: The phrase uses the comparison of the moon to a rocking motion to evoke an image of movement and instability within the stormy cloud. It doesn't use "like" or "as" as in a simile, nor does it repeat the same words as in repetition, making it a metaphor.
By understanding the definition and characteristics of a metaphor, we can identify how the given phrase fits this literary device by creating a vivid image through indirect comparison.
