Secondly, it is not entirely correct to say that poetry has no format. So far, there are ancient poems and modern poems, and words, songs and sonnets have rhyme.
Third, it is not the form of poetry to break an essay into a sentence. The form of poetry is not only a sentence and a paragraph, but also punctuation marks and spaces, as well as the synthesis of fresh words and contents. This is poetry. Poetry is a spiritual discipline, remember!
Finally, many people tend to classify poetry similar to prose and prose similar to poetry as "prose poetry", which is wrong. Prose poetry has the genre of prose poetry, and we don't just name it.
