What term is used to describe the repetition of the same consonant sounds or beginning several words with the same vowel sound?

The term that best describes the repetition of the same consonant sounds or the beginning of several words with the same vowel sound is alliteration. Alliteration specifically refers to the occurrence of the same initial consonant sound in a series of words, often used for poetic effect or to enhance rhythm in language.

In this case, alliteration highlights the impact of sound in writing, drawing attention to specific phrases or passages and creating a musical quality that can engage readers and enhance the overall mood of a piece. It is commonly found in poetry, prose, and song lyrics where the repetition of initial sounds can deepen the reader's experience.

Other terms presented are not appropriate for defining this specific sound repetition. Assonance refers to the repetition of vowel sounds within nearby words, while consonance involves the repetition of consonant sounds in close proximity, but not specifically at the beginning of words. Rhyme pertains to the correspondence of sounds, typically at the end of words, rather than the initial sounds being discussed in this question.
