What defines alliteration in literature?

Alliteration is defined as the repetition of initial sounds in neighboring words. This literary device is often utilized to create rhythm, enhance mood, and draw attention to particular phrases or ideas within a text. For example, in phrases like "wild and windy," the repetition of the 'w' sound enhances the auditory quality of the language, making it more engaging and memorable. Alliteration can be found in various forms of literature, including poetry and prose, contributing to the work's overall aesthetic and sound.

The other options, while they represent valid literary concepts, do not align with the definition of alliteration. Metaphors focus on the comparison of unlike things, rhythm and metrics deal with the flow of poetry rather than sound repetition, and the arrangement of words for suspense pertains to narrative structure rather than sound effects. Thus, the focus on initial sounds in neighboring words is what distinctly characterizes alliteration.
