rhyme or rime, the most prominent of the literary artifices used in versification . Although it was used in ancient East Asian poetry, rhyme was practically unknown to the ancient Greeks and Romans. With the decline of the classical quantitative meters and the substitution of accentual meters, rhyme began to develop, especially in the sacred Latin poetry of the early Christian church. In the Middle Ages, end rhyme (rhyme at the end of a line), assonance (repetition of related vowel sounds), and alliteration (repetition of consonants, particularly at the beginning of words) were predominant in vernacular verse. After 1300 rhyme came to be the outstanding metrical mark of poetry until the introduction of blank verse in the 16th cent. Alliteration and assonance were both called rhyme by early writers, but today two words are said to rhyme only when the sound of the final accented syllable of one word (placed usually at the end of a line of verse) agrees with the final accented syllable of another word so placed. When the vowels in the final accented syllables of the two rhyming words and the consonants (if any) succeeding the vowel have exactly the same sound, it is called perfect rhyme, e.g., shroud and cloud, mark and bark. Many poets, however, particularly 20th-century poets, use imperfect or approximate rhymes, in which the rhymed vowels and even the consonants might be similar but not identical, e.g., groaned and ground. Two words cannot rhyme unless both...
