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.
