Which literary device involves the repetition of the same initial consonant sound in a series of words?

The literary device that involves the repetition of the same initial consonant sound in a series of words is known as alliteration. This technique is often used in poetry and prose to create rhythm, enhance mood, or emphasize certain phrases or concepts. By starting several words with the same consonant, alliteration can produce a musical quality that makes the text more engaging and memorable. For example, phrases like "whispering winds" and "sizzling sausages" illustrate how alliteration can vividly evoke imagery and sound.

Assonance, in contrast, focuses on the repetition of vowel sounds within words rather than consonants. Consonance involves the repetition of consonant sounds, but it can occur at the end or in the middle of words, not just at the beginning. Onomatopoeia refers to words that imitate natural sounds, such as "buzz" or "bang." Each of these devices serves a different purpose in language, but alliteration specifically hones in on initial consonant sounds, distinguishing it as the correct answer to the question.
