If the sound preceding the stressed vowel is also identical, the rhyme is sometimes considered to be inferior and not a perfect rhyme after all. An 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").
