How is "alliteration" defined in writing?

Alliteration is defined as the repetition of the same sound at the beginning of adjacent or closely connected words. This literary device is often used to create a musical quality in writing, enhance flow, and emphasize specific phrases or ideas. It can help to draw attention to a particular section of text, making it more memorable or impactful.

For example, in a phrase like "wild and windy," the repetition of the 'w' sound not only creates a rhythm but also evokes a certain imagery. This technique is frequently employed in poetry, prose, and even advertising to reinforce concepts and generate a pleasing sound pattern that engages readers.
