What rhetorical device is prominently used in both the "I Have a Dream" speech and the "Gettysburg Address"?

Repetition is a powerful rhetorical device employed in both the "I Have a Dream" speech by Martin Luther King Jr. and the "Gettysburg Address" by Abraham Lincoln. In King's speech, he famously repeats the phrase "I have a dream" to emphasize his vision for a racially integrated and harmonious America. This repetition not only reinforces the central theme of his message but also creates a rhythmic quality that enhances its emotional impact, making it memorable and uplifting.

Similarly, in the "Gettysburg Address," Lincoln uses repetition to underscore key ideas and values, such as liberty and equality. By carefully repeating elements of his speech, he draws attention to the ideals for which those who fought at Gettysburg sacrificed their lives, emphasizing the significance of the occasion and invoking a sense of national unity.

The use of repetition in both speeches serves to engage the audience, strengthen the emotional resonance of the speakers' messages, and ensure that the core themes of hope and remembrance linger in the minds of listeners.
