Rhythm of English Poetry
In traditional English poetry, the rule of rhyme is that the vowels of the stressed syllables of two mutually rhyming words are the same, and all the sounds after the stressed syllables are the same. For example, hollowing out, here are two words that strictly conform to the rhyme law. In the romantic period, the rules of rhyme were slightly relaxed, and sometimes even rhymed as long as the last syllable of two words was the same, like power and flower. But it was not until the second world that it really became popular. In the 20th century, some poets were more free, even the vowels of the last syllable were different, but the same gospel rhymed, such as last and lost.
