Alliteration is the repetition of identical sounds at the beginning of words or in stressed syllables. The words applied in alliteration can begin with a consonant or a vowel. This literary device occurs in various words across successive sentences, clauses, or phrases. The function of alliteration, like rhyme, might be to emphasize the exquisiteness of language in a given context, or to unite words or concepts through a type of repetition.

"We, the people, declare today that the most evident of truths — that all of us are created equal — is the star that guides us still; just as it guided our forebears through Seneca Falls, and Selma, and Stonewall; just as it guided all those men and women, sung and unsung, who left footprints along this great Mall, to hear a preacher say that we cannot walk alone; to hear a King proclaim that our individual freedom is inextricably bound to the freedom of every soul on Earth." -Barack Obama
"I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character." -MLK
