What is the literary device that involves the repetition of initial sounds in neighboring words?

The correct answer is alliteration, which is the literary device that involves the repetition of initial consonant sounds in neighboring words. This device creates a musical quality in language and can enhance the mood or tone of a piece of writing. For example, phrases like "whispering winds" or "sailing seas" exemplify alliteration by repeating the initial 'w' and 's' sounds.

This technique is commonly used in poetry, prose, and even in speeches to make the text more engaging and memorable. When authors employ alliteration, it can evoke emotion or emphasize a particular theme.

Other options like assonance refer to the repetition of vowel sounds within nearby words, but they do not focus on the initial sounds. Consonance involves the repetition of consonant sounds, but it can occur anywhere within the words, not specifically at the beginning. Repetition refers to the use of the same word or phrase multiple times, which is not limited to initial sounds. Thus, alliteration distinctly emphasizes the repetition at the start of words, making it the clear choice for this question.
