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; for polysyllabic words, rhymes are the exception rather than the rule.
