Answer:
Figurative language refers to figures of speech (metaphor, irony, personification, etc.) we use in order to make our text more effective and impactful. Its use is very common at the soliloquies for different reasons.
First of all, a figurative language can be used to draw the attention of the reader or observer to action in a play or a novel. The use of the figurative language in the soliloquies is frequently accompanied by strong dramatical effects. Therefore, we could also say that figurative language is used to emphasize some of the most important character thoughts, feelings, and inner struggles, as for example in <em>Hamlet </em>soliloquies where we can find madness, hesitation, and the strong inner struggle between good and evil.
On the other hand, figurative language can be used in order to embellish the writing and make it more literary, stylized, and sophisticated.
