What are polyphony, reduplication, iconicity and reduplication in poetry?

Simply put.

Disyllabic words are simple words with the same initials; For example: embarrassed

Overlapping refers to two simple words with the same vowel; For example: wandering

Image sound is a simple word that imitates sound; For example: Alas, I am babbling, and I am humming.

Overlap is two simple words with the same pronunciation. Close and complain.

Attention refers to simple words, that is, words that are meaningless separately and interesting together. That's not what compound words are usually called.

Please note again that some words are both disyllabic and rhyming. Some words are both phonetic and reduplicative. So the examples are also cross.
