Is there a prefix for alliteration?

There isn't a specific prefix for alliteration. However, you could use a general prefix like "allo-" or "omni-" to create a term that implies the repetition of sounds. Here are some possibilities:

* Alloprosody: This combines "allo-" (meaning "other" or "different") with "prosody," which refers to the rhythm and sound of language.

* Omniphone: This combines "omni-" (meaning "all") with "phone," which refers to sound.

* Panphone: This combines "pan-" (meaning "all") with "phone," which refers to sound.

These terms might not be widely accepted or used, but they would convey the idea of repetition of sounds in a way that highlights the "all" aspect of alliteration.

Ultimately, it's up to you to choose the most appropriate term depending on the context of your writing.
