Alliteration is a literary device in which a series of words or phrases begin with the same sound, usually a consonant. Alliteration is often used in poetry and other types of writing to add rhythm, rhyme, and musicality to the language.

For example, the phrase “Peter Piper picked a peck of pickled peppers” is an example of alliteration, as all of the words begin with the letter “p.” Alliteration can also involve the repetition of vowel sounds, such as in the phrase “A proper copper coffee pot.”
