Assonance

Assonance is the repetition of vowel sounds to create internal rhyming within phrases or sentences, and together with alliteration and consonance serves as one of the building blocks of verse. For example, in the phrase "Do you like blue?", the ("o"/"ou"/"ue" sound) is repeated within the sentence and is assonant.

Assonance is found more often in verse than in prose. It is used in (mainly modern) English-language poetry, and is particularly important in Old French, Spanish and the Celtic languages.

The eponymous student of Willy Russell's Educating Rita described it as "getting the rhyme wrong".

Examples
J. R. R. Tolkien's Errantry is a poem whose meter contains three sets of trisyllabic assonances in every set of four lines.

Assonance can also be used in forming proverbs, often a form of short poetry. In the Oromo language of Ethiopia, note the use of a single vowel throughout the following proverb, an extreme form of assonance:
 * kan mana baala, aʔlaa gaala (“A leaf at home, but a camel elsewhere"; somebody who has a big reputation among those who do not know him well.)

In more modern verse, stressed assonance is frequently used as a rhythmic device in modern rap. An example is Public Enemy's 'Don't Believe The Hype': ''"Their pens and pads I snatch 'cause I've had it / I'm not an addict, fiending for static / I see their tape recorder and I grab it / No, you can't have it back, silly rabbit".
