What are stylistic devices?
In literature and writing, a stylistic device (also called figure of speech or rhethorical device) is the use of any of a variety of techniques to give an auxiliary meaning, idea, or feeling. Sometimes a word diverges from its normal meaning, or a phrase has a specialized meaning not based on the literal meaning of the words in it. Examples are metaphor, simile, or personification. Stylistic devices often provide emphasis, freshness of expression, or clarity.
