Assonance is the repetition of identical or similar phonemes in words or syllables that occur close together, either in terms of their vowel phonemes (e.g., lean green meat) or their consonant phonemes (e.g., Kip keeps capes ).[1] However, in American usage, assonance exclusively refers to this phenomenon when affecting vowels, whereas, when affecting consonants, it is generally called consonance.[2] The two types are often combined, as between the words six and switch, which contain the same vowel and similar consonants. If there is repetition of the same vowel or some similar vowels in literary work, especially in stressed syllables, this may be termed "vowel harmony" in poetry[3] (though linguists have a different definition of "vowel harmony").
A special case of assonance is rhyme, in which the endings of words (generally beginning with the vowel sound of the last stressed syllable) are identical—as in fog and log or history and mystery. Vocalic assonance is an important element in verse.[4] Assonance occurs more often in verse than in prose; it is used in English-language poetry and is particularly important in Old French, Spanish, and the Celtic languages.
Examples
English poetry is rich with examples of assonance and/or consonance:
Some vodka that'll jumpstart my heart quicker than a shock when I get shocked at the hospital by the doctor when I'm not cooperating when I'm rocking the table when he's operating...
Total assonance is found in a number of Pashto proverbs from Afghanistan:
La zra na bal zra ta laar shta. "From one heart to another there is a way."[5]
Kha ghar lwar day pa sar laar lary. "Even if a mountain is very high, there is a path to the top."[6]
This poetic device can be found in the first line of Homer's Iliad: Mênin áeide, theá, Pēlēïádeō Akhilêos (Μῆνιν ἄειδε, θεά, Πηληϊάδεω Ἀχιλῆος). Another example is Dies irae (probably by Thomas of Celano):
All rhymes in a strophe can be linked by vowel harmony into one assonance. Such stanzas can be found in Italian or Portuguese poetry, in works by Giambattista Marino and Luís Vaz de Camões:
