List of English words without rhymes

The following is a list of English words without rhymes, called refractory rhymes—that is, a list of words in the English language that rhyme with no other English word. The word "rhyme" here is used in the strict sense, called a perfect rhyme, that the words are pronounced the same from the vowel of the main stressed syllable onwards. The list was compiled from the point of view of Received Pronunciation (with a few exceptions for General American), and may not work for other accents or dialects. Multiple-word rhymes (a phrase that rhymes with a word, known as a phrasal or mosaic rhyme), self-rhymes (adding a prefix to a word and counting it as a rhyme of itself), imperfect rhymes (such as purple with circle), and identical rhymes (words that are identical in their stressed syllables, such as bay and obey) are often not counted as true rhymes and have not been considered. Only the list of one-syllable words can hope to be anything near complete; there are many disyllabic or polysyllabic words without rhymes.

Definition of perfect rhyme

Following the strict definition of rhyme, a perfect rhyme demands the exact match of all sounds from the last stressed vowel to the end of the word. Therefore, words with the stress far from the end are more likely to have no perfect rhymes. For instance, a perfect rhyme for discomBOBulate would have to rhyme three syllables, -OBulate. There are many words that match most of the sounds from the stressed vowel onwards and so are near rhymes, called slant rhymes. Ovulate, copulate, and populate, for example, vary only slightly in one consonant from discombobulate, and thus provide very usable rhymes for most situations in which a rhyme for discombobulate is desired.
