(_ββ_) _Secondly_, _assonance_ has nothing to do with initial letters, but makes a nearer approach to rhyme in so far as it is a recurrence in identical sound of the same letters in the middle or at the termination of different words. It is not necessary, of course, that these assonant words should in all cases come at the conclusion of a line; they may fall into other places. Mainly, however, it is the concluding syllables of lines which come into this mutual relation of assonance, as contrasted with alliteration which is effective rather at the line's commencement. In its richest elaboration we may associate this assonance of language with the Romance nations, more especially the Spanish, whose full-toned language is peculiarly adapted to this recurrence of the same vowels. As a rule, no doubt assonance is here restricted to vowels. But the language further permits of other variety of assonance, not only that of vowels, but also that of identical consonants and consonants in association with one vowel. (_γγ_) That which, as above described, alliteration and assonance are only able to establish with incompleteness is abundantly fulfilled by _rhyme._ In it, and expressly to the exclusion of initial letters, we have asserted the wholly equable sound of entire verb stems,[49] which are, by virtue of this equability, brought into an express relation with their tonal utterance. We have no mere question now of the number of the syllables. Words of one syllable, no less than others of two or more, may be rhymed. By this means we not only get the masculine rhyme, which is restricted to words of one syllable, but also the feminine rhyme, which embraces words of two syllables, as also the so-called gliding rhyme, which reaches to three or even more syllables. It is in particular the languages of Northern Europe which incline to the first type, Southern languages to the second, such as the Italian and Spanish. The German and French languages would appear to lie between these two extremes. Rhymes of more than three syllables are rarely to be met with in any language.
