Rhyme which satisfies certain conditions on the phonemes of the words involved
Perfect rhyme — also called full rhyme, exact rhyme,[1] or true rhyme — is a form of rhyme between two words or phrases, satisfying the following conditions:[2][3]
The stressed vowel sound in both words must be identical, as well as any subsequent sounds. For example, the words "kit" and "bit" form a perfect rhyme.[4][5]
The onset of the stressed syllable in the words must differ. For example, "pot" and "hot" are a perfect rhyme, while "leave" and "believe" are not.
Word pairs that satisfy the first condition but not the second (such as the aforementioned "leave" and "believe") are technically identities (also known as identical rhymes or identicals). Homophones, being words of different meaning but identical pronunciation, are an example of identical rhyme.[3]
Imperfect rhyme
"Sprung rhyme" redirects here. Not to be confused with Sprung rhythm.
Half rhyme or imperfect rhyme, sometimes called near-rhyme, lazy rhyme, or slant rhyme, is a type of rhyme formed by words with similar but not identical sounds. In most instances, either the vowel segments are different while the consonants are identical, or vice versa. This type of rhyme is also called approximate rhyme, inexact rhyme, imperfect rhyme (in contrast to perfect rhyme), off rhyme, analyzed rhyme, suspended rhyme, or sprung rhyme.[6][7][8][9]
Half rhyme is often used, along with assonance, in rap music. This can be used to avoid rhyming clichés (e.g., rhyming "knowledge" with "college") or obvious rhymes and gives the writer greater freedom and flexibility in forming lines of verse. Additionally, some words have no perfect rhyme in English, necessitating the use of slant rhyme.[11] The use of half rhyme may also enable the construction of longer multisyllabic rhymes than otherwise possible.[12]
In the following lines from the song "N.Y. State of Mind" by rapper Nas, the author uses half rhyme in a complex cross rhyme pattern:
And be prosperous, though we live dangerous Cops could just arrest me, blamin' us, we're held like hostages
Unconventional exceptions
Children's nursery rhyme This Little Piggy displays an unconventional case of slant rhyme. "Home" is rhymed with "none".
This little piggy stayed (at) home...this little piggy had none.
