* Onomatopoeia: This is the use of words that imitate the sounds they represent (e.g., "buzz", "hiss"). Alliteration is about the repetition of sounds at the beginnings of words.
* Cognate: This refers to words that have a common origin and share similarities in form and meaning (e.g., "father" in English and "padre" in Spanish). Alliteration is a stylistic device, not related to word origins.
* Palindrome: This is a word or phrase that reads the same backward as forward (e.g., "racecar"). Alliteration is about sounds, not reversed word structure.
* Eponym: This is a person, place, or thing after whom something is named (e.g., the city of Washington is named after George Washington). Alliteration is a literary device, not a naming convention.
In summary: Alliteration is a literary device involving the repetition of initial consonant sounds in closely positioned words. It's distinct from the other terms listed.
