* To create a vivid picture of the action. Shakespeare's plays are full of action, and the language he uses helps to create a vivid picture of what is happening. For example, in the play "Hamlet," the character of Hamlet describes the ghost of his father as follows:
```
His beard was grizzled, no longer black;
His eye as bright as a falcon's, fierce and keen;
His face was pale, but not with sickness,
But as 'twere with the grief of years;
His voice was low and deep, but clear and distinct.
```
This description is so detailed that the reader can easily imagine what the ghost of Hamlet's father looks like.
* To convey the characters' emotions. Shakespeare's plays are also full of emotion, and the language he uses helps to convey the characters' feelings. For example, in the play "Romeo and Juliet," the character of Juliet expresses her love for Romeo as follows:
```
O Romeo, Romeo, wherefore art thou Romeo?
Deny thy father and refuse thy name;
Or, if thou wilt not, be but sworn my love,
And I'll no longer be a Capulet.
```
Juliet's words are so passionate that the reader can feel her love for Romeo.
* To create a sense of atmosphere. Shakespeare's plays are also full of atmosphere, and the language he uses helps to create this atmosphere. For example, in the play "Macbeth," the character of Macbeth describes the witches he meets as follows:
```
When shall we three meet again
In thunder, lightning, or in rain?
When the hurlyburly's done,
When the battle's lost and won.
```
The language in this passage creates a sense of foreboding and mystery, which is appropriate for the scene in which it occurs.
In addition to these reasons, the language in Shakespeare's plays is also highly poetic. This means that it is full of imagery, figurative language, and other rhetorical devices. This poetic language helps to make Shakespeare's plays more beautiful and memorable.
