In “I Have a Dream,” Martin Luther King, Jr. uses a rhetorical device called anaphora, which is the repetition of a word or phrase in order to add emphasis to a central or main idea. For example, in paragraph six, King repeats the phrase “now is the time” to emphasize the urgency with which the country should act to ensure true freedom for African Americans. Identify three other examples of anaphora in “I Have a Dream.” In an essay of 250 words or more, explain what each example emphasizes and how it contributes meaning and tone to the speech. How does the use of anaphora focus the reader or listener on the central themes of the speech? Support your answer with evidence from the text.
