Perfect rhyme occurs when the final stressed syllables of two or more words have identical sounds, including both the vowel and any following consonants. For example, the words cat and hat are perfect rhymes because they share the same ending sound. This type of rhyme is commonly used in poetry and song lyrics to create a pleasing auditory effect. In addition to enhancing the rhythm and flow of a piece, perfect rhyme can also contribute to its overall meaning and emotional impact. Poets and songwriters often choose perfect rhymes to emphasize key themes or ideas, making their work more memorable and engaging for the audience.
