§ =11.= This last, end-rhyme, or full-rhyme, or rhyme proper, consists in a perfect agreement or consonance of syllables or words except in their initial sounds, which as a rule are different. Generally speaking, the agreement of sounds falls on the last accented syllable of a word, or on the last accented syllable and a following unaccented syllable or syllables. End-rhyme or full-rhyme seems to have arisen independently and without historical connexion in several nations, but as far as our present purpose goes we may confine ourselves to its development in Europe among the nations of Romanic speech at the beginning of the Middle Ages. Its adoption into all modern literature is due to the extensive use made of it in the hymns of the Church. Full-rhyme or end-rhyme therefore is a characteristic of modern European poetry, and though it cannot be denied that unrhymed verse, or blank verse, is much used in English poetry, the fact remains that this metre is an exotic product of the Renaissance, and has never become thoroughly popular. Its use is limited to certain kinds of poetic composition, whereas rhyme prevails over the wider part of the realm of modern poetry. § =12.= The second kind of rhyme (taking the word in its broader sense), namely, vocalic assonance, is of minor importance in the treatment of English metre. It consists in a similarity between the vowel-sounds only of different words; the surrounding consonants do not count. The following groups of words are assonant together: _give_, _thick_, _fish_, _win_; _sell_, _step_, _net_; _thorn_, _storm_, _horse_. This kind of rhyme was very popular among the Romanic nations, and among them alone. Its first beginnings are found in the Latin ecclesiastical hymns, and these soon developed into real or full-rhyme.[12] It passed thence into Provençal, Old French, and Spanish poetry, and has continued in use in the last named. It is very rarely found in English verse, it has in fact never been used deliberately, as far as we know, except in certain recent experiments in metre. Where it does seem to occur it is safest to look upon it as imperfect rhyme only. Instances are found in the Early English metrical romances, Lives of Saints, and popular ballad poetry, where the technique of the metre is not of a high order; examples such as _flete_, _wepe_; _brake_, _gate_; _slepe_, _ymete_ from _King Horn_ might be looked on as assonances, but were probably intended for real rhymes. The consistent use of the full-rhyme being difficult, the poets, in such instances as these, contented themselves with the simpler harmony between the vowels alone, which represents a transition stage between the older rhymeless alliterative verse, and the newer Romanic metres with real and complete rhyme. Another possible form of assonance, in which the consonants alone agree while the vowels may differ, might be called _consonantal assonance_ as distinguished from _vocalic assonance_, or assonance simply.
