"Juliet is the sun "is the example of
The phrase "Juliet is the sun" is an example of figurative language. More specifically, it is an example of a metaphor. A metaphor is a figure of speech that makes a comparison between two things that are not alike but have something in common. In this case, the speaker is comparing Juliet to the sun. The intended meaning is that Juliet is the source of light, warmth, and happiness, just like the sun.
To identify this as a metaphor, you can look for key words or phrases that indicate a comparison. In this case, the use of "is" suggests that Juliet is being equated to the sun. Additionally, the phrase does not make sense if interpreted literally, as we know that Juliet is a human being and cannot actually be a celestial body. Instead, we need to understand it as a metaphorical statement that uses the qualities and associations of the sun to describe Juliet.
