The repetition of the same consonant sound at the beginning of words or stressed syllables in a phrase or sentence.
Here's why:
* Consonant Sound: It's the *sound* of the consonant, not the letter itself, that matters. For example, "Peter Piper picked a peck of pickled peppers" has the alliteration on the "p" sound, even though the words "picked" and "peck" start with different letters.
* Beginning of Words or Stressed Syllables: Alliteration can occur at the start of words ("Peter Piper") or the start of stressed syllables ("a peck of pickled peppers").
* Phrase or Sentence: It's a stylistic device used to enhance the sound and rhythm of phrases or sentences.
