rhyme. the identity of sound between syllables or paired groups of syllables, usually at the ends of verse lines; also a poem employing this device. Normally the last stressed vowel in the line and all sounds following it make up the rhyming element: this may be a monosyllable (love/aboveknown as 'masculine rhyme'), or two syllables (whether/togetherknown as 'feminine rhyme' or 'double rhyme'), or even three syllables (glamorous/amorous - known as 'triple rhyme'). Where a rhyming element in a feminine or triple rhyme uses more than one word (famous/shame us), this is known as a 'mosaic rhyme'. The rhyming pairs illustrated so far are all examples of 'full rhyme' (also called 'perfect rhyme' or 'true rhyme'): departures from this norm take three main forms: (i) rime riche, in which the consonants preceding the rhyming elements are also identical, even if the spellings and meanings of the words differ (made/maid): (ii) eye rhyme. in which the spellings of the rhyming elements match, but the sounds do not (love/prove); (iii) 'half-rhyme or 'slant rhyme,' where the vowel sounds do not match (love/have, or, with rich consonance, love/leave). Half-rhyme is known by several other names: 'imperfect rhyme', 'near rhyme', 'pararhyme,' etc. Although rhyme is most often used at the ends of verse lines, internal rhyme between syllables within the same line is also found. Rhyme is not essential to poetry: many languages rarely use it, and in English it finally replaced alliteration as the usual patterning device of verse only in the late 14th century. A writer of rhyming verse may sometimes be referred to disparagingly as a rhymester or rhymer.
