What literary device is defined by using words of similar meaning?

The correct answer is the use of synonyms, which refers to words that have similar meanings. This literary device is vital in enhancing writing and communication, as it allows for variety in expression while maintaining the same idea. By incorporating synonyms, a writer can avoid repetition, create a more engaging narrative, and provide nuance to the text. For example, instead of repeatedly using the word "happy," a writer might switch to "joyful" or "content" to convey the same sentiment in different contexts.

The understanding of synonyms is essential in both literary analysis and language proficiency, as it can enrich vocabulary and improve comprehension. Recognizing that various words can convey similar meanings allows readers and writers to explore language depthfully, fostering creativity and effective expression.
