The use of figurative language runs rampant throughout William Shakepeare's play Romeo and Juliet (in a positive and beautiful way). In the balcony scene, many examples of metaphors, similes, and personification can be found.
Metaphors-comparison between two things not using "like" or "as" to make the comparison.
"But soft! What light through yonder window breaks?" Here, Romeo is comparing Juliet's entrance onto the balcony as the sun rising. To compound this metaphor, Romeo actually calls Juliet the sun (in another example of a metaphor): "Juliet is the sun!"
Simile- the comparison between two things using "like" or "as" to make the comparison.
O, speak again, bright angel! for thou art
As glorious to this night, being o'er my head,
As is a winged messenger of heaven.
Here, Juliet is compared to a winged messenger of heaven. Given that the comparison uses the word "as," this comparison is a simile.
Personification - the giving of human characteristics/abilities to non-living and non-human things.
Arise, fair sun, and kill the envious moon,
Who is already sick and pale with grief.
Here, the sun and moon are both personified (given the sun is allotted the ability to kill the moon and to be sick/pale with grief).
Another example of personification is: "When he bestrides the lazy-pacing clouds." Here, the clouds are given the ability to be lazy and pacing.
Another example of personification can be found when Romeo declares his name to be his enemy.
'Tis but thy name that is my enemy.
My name, dear saint, is hateful to myself,
Because it is an enemy to thee.
Later, Juliet also gives human characteristics to something which only humans can do. Juliet states that her ears can drink.
My ears have yet not drunk a hundred words.
Metaphor: It is the east, and Juliet is the sun.
Simile: My bounty is as boundless as the sea, my love as deep
Personification: Arise, fair sun, and kill the envious moon,
Who is already sick and pale with grief
That thou her maid art far more fair than she.
