Alliteration is a literary device that involves the repetition of the same sound at the beginning of words in close proximity to each other
. This sound can be a consonant or a vowel, but it is usually a consonant. Alliteration is often used in poetry, literature, music lyrics, and advertising to create a rhythmic effect and make phrases more memorable. Examples of alliteration include "Peter Piper picked a peck of pickled peppers" and "She sells seashells by the seashore"
