Alliteration is a literary device where two or more words in a phrase or sentence start with the same sound.
Here are some examples:
* She sells seashells by the seashore.
* Peter picked a peck of pickled peppers.
* With winds that whisper, we walk the wooded way.
Alliteration can be used to:
* Create a catchy and memorable phrase.
* Emphasize certain words or phrases.
* Add a sense of rhythm and flow to writing.
* Create a playful or whimsical tone.
It's important to use alliteration sparingly, as overuse can sound forced or artificial.
