example of such a super-rhyme or "more than perfect rhyme" is the identical rhyme, in which not only the vowels but also the onsets of the rhyming syllables are identical, as in gun and begun. Punning rhymes, such as bare and bear are also identical rhymes. The rhyme may extend even farther back than the last stressed vowel. If it extends all the way to the beginning of the line, so that there are two lines that sound very similar or identical, it is called a holorhyme ("For I scream/For ice cream"). In poetics these would be considered identity, rather than rhyme. Eye rhyme Eye rhymes or sight rhymes or spelling rhymes refer to similarity in spelling but not in sound where the final sounds are spelled identically but pronounced differently. Examples in English are cough, bough, and love, move. Some early written poetry appears to contain these, but in many cases the words used rhymed at the time of writing, and subsequent changes in pronunciation have meant that the rhyme is now lost. Mind rhyme Mind rhyme is a kind of substitution rhyme similar to rhyming slang, but it is less generally codified and is “heard” only when generated by a specific verse context. For instance, “this sugar is neat / and tastes so sour.” If a reader or listener thinks of the word “sweet” instead of “sour,” a mind rhyme has occurred. Classification by position Rhymes may be classified according to their position in the verse: Tail rhyme (also called end rhyme or rime couée) is a rhyme in the final syllable(s) of a verse (the most common kind). Internal rhyme occurs when a word or phrase in the interior of a line rhymes with a word or phrase at the end of a line, or within a different line. Off-centered rhyme is a type of internal rhyme occurring in unexpected places in a given line. This is sometimes called a misplaced-rhyme scheme or a spoken word rhyme style. Holorime, mentioned above, occurs when two entire lines have the same sound. Broken rhyme is a type of enjambement producing a rhyme by dividing a word at the line break of a poem to make a rhyme with the end word of another line. Cross rhyme matches a sound or sounds at the end of a line with the same sound or sounds in the middle of the following
