List of English words without rhymes

Summary

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.

Definition of perfect rhyme edit

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. However, no other English word has exactly these three final syllables with this stress pattern.[1] And since in most traditions the stressed syllable should not be identical—the consonant before the stressed vowel should be different—adding a prefix to a word, as be-elbow for elbow, does not create a perfect rhyme for it.

Words that rhyme in one accent or dialect may not rhyme in another. A commonplace example of this is the word of /ɒv/, which when stressed had no rhymes in British Received Pronunciation prior to the 19th century, but which rhymed with grave and mauve in some varieties of General American.[2] In the other direction, iron has no rhyme in General American, but many in RP. Words may also have more than one pronunciation, one with a rhyme, and one without.

Non-rhyming English words edit

The majority of words with antepenultimate stress, such as ambulance,[19] citizen, dangerous and obvious, and with preantepenultimate stress, such as (un)necessary, logarithm, algorithm and sacrificing, have no rhyme.

Masculine rhymes edit

Refractory one-syllable rhymes are uncommon; there may be fewer than a hundred in English.[20] A great many end in a present or historical suffix -th, or are plural or participle forms. This list includes a few polysyllabic masculine rhymes such as obliged, which have one syllable in their rhyming part.[21]

  1. adzed /ˈ-ædzd/
  2. airt (rhymes with the Scots pronunciations of a number of other words, e.g. "pairt",[22] a Scots variant of "part")
  3. alb /-ælb/[23] (rhymes with some pronunciations of the proper noun "Kalb"[24] in the name of Johann de Kalb)
  4. amongst /-ʌŋst/ ("quincunxed" could qualify as a rhyme if its second syllable is given secondary stress and if secondary stress is considered sufficient for a perfect rhyme)
  5. angsts /ˈ-æŋksts/[25]
  6. bilge /ˈ-ɪl/
  7. boinged /ˈ-ɔɪŋd/
  8. borscht /ˈ-ɔːrʃt/ (could rhyme with a dialectal North American pronunciation of "washed" as "worshed/warshed"[26])
  9. borshch /- ɔrʃtʃ/ (pronunciation variant of the above)
  10. breadth, -s /ˈ-ɛdθ, -s/
  11. bronzed /ˈ-ɒnzd/
  12. bulb, -s, -ed /ˈ-ʌlb, -z, -d/[27]
  13. calced /ˈ-ælst/ (may rhyme with "valsed" in British English, according to the Oxford English Dictionary)
  14. combs (combinations) /ˈ-ɒmbz/
  15. coolth /ˈ-lθ/
  16. corpsed /ˈ-ɔːrpst/
  17. culm /ˈ-ʌlm/
  18. delft /ˈ-ɛlft/
  19. depth, -s /ˈ-ɛpθ, -s/
  20. dreamt (sometimes pronounced /ˈ-ɛmpt/, causing "dreamt" to rhyme with exempt, tempt, etc.)
  21. dumbth /ˈ-ʌmθ/
  22. eighth, -s /ˈ-tθ, -s/
  23. excerpts (verb) /ˈ-ɜːrpts/
  24. false /ˈ-ɔːls/[28]
  25. fifth, -ed, -s /ˈ-ɪfθ, -t, -s/
  26. filmed /ˈ-ɪlmd/[29]
  27. glimpsed /ˈ-ɪmpst/
  28. goonch /ˈ-ʊn/
  29. gouge(d) /ˈ-/
  30. (en)gulfed /ˈ-ʌlft/
  31. kilned /ˈ-ɪlnd/ (but not when pronounced as /ˈ-ɪld/)
  32. kirsch /ˈ-ɪərʃ/
  33. midsts /ˈ-ɪdsts/
  34. mulcts /ˈ-ʌlkts/[30]
  35. ninth, -s /ˈ-nθ, -s/
  36. obliged /ˈ-d/
  37. obvs /ˈ-ɒbvz/
  38. oomph /ˈ-mf/
  39. pierced /ˈ-ɪərst/
  40. prompts /ˈ-ɒmts/ or /ˈ-ɒmpts/
  41. scarce /ˈ-ɛərs/
  42. sculpts /ˈ-ʌlpts/
  43. sixth, -s /ˈ-ɪksθ, -s/
  44. sowthed, southed /ˈ-θt/[31]
  45. spoilt /ˈ-ɔɪlt/
  46. stilb /ˈ-ɪlb/
  47. swoln /ˈ-ln/
  48. traipsed /ˈ-pst/
  49. twelfth, -s /ˈ-ɛlfθ, -s/ The "f" in "twelfth" is commonly elided in casual speech, causing "twelfth" to rhyme with "health" and "wealth".
  50. unbeknownst /ˈ-nst/
  51. vuln, -ed, -s /ˈ-ʌln, -d, -z/
  52. warmth /ˈ-ɔːrmθ/
  53. whilst /ˈ-lst/
  54. with /ˈ-ɪð/ (the word is also pronounced with /ˈ-ɪθ/, in which case it has rhymes like "pith")
  55. wolf, -ed, -s /ˈ-ʊlf, -t, -s/
  56. wolve, -d, -s /ˈ-ʊlv, -d, -z/
  57. worlds /ˈ-ɜːrldz/
  58. wounds /ˈ-ndz/
  59. yoicks, joik, -s /ˈ-ɔɪks/

pork /ˈ-rk/ and forge /ˈ-r/ have no rhymes in conservative RP.[32] However, the distinction between horse and hoarse has been mostly lost in younger generations, and for them and many others pork which was an exception to the normal rule, now rhymes with fork and cork (/ˈ-ɔːrk/), while forge now rhymes with gorge. The OED no longer lists /pɔək/ as an alternative pronunciation in its third edition.

Nonce words ending in -ed ('provided with') may produce other potentially refractory masculine rhymes.[33] There are additional words which are only partially assimilated into English, such as Russian kovsh /ˈkɒvʃ/, which are refractory rhymes.

The contraction daren't /ˈ-ɛərnt/ has no known rhymes in any English dialect, however the legitimacy of contractions as a single word is disputed. Regardless of this, daren't lacks both perfect rhymes and phrasal rhymes.

Although not meant as a complete list, there are some additional refractory rhymes in GA. Some of these are due to RP being a non-rhotic accent, and having merged rhymes formerly distinguished by /r/.

  1. heighth, -s /ˈ-tθ, -s/[34]
  2. iron /ˈ-aɪərn/[35]
  3. karsts /ˈ-ɑːrsts/[36]

Feminine rhymes edit

For feminine rhymes, the final two syllables must match to count as a rhyme. Once the stress shifts to the penultimate syllable, rhymeless words are quite common, perhaps even the norm: there may be more rhymeless words than words with rhymes.[37] The following words are representative, but there are thousands of others.

  1. angel
  2. angry [38]
  3. anxious
  4. chimney
  5. comment
  6. empty [39]
  7. engine [40]
  8. foible
  9. foyer[41]
  10. hundred(th)
  11. husband
  12. liquid
  13. luggage [42]
  14. monster
  15. nothing
  16. olive
  17. penguin
  18. polka [43]
  19. problem
  20. sanction
  21. sandwich
  22. secret
  23. something [44]
  24. zigzag

  1. ^ OED search for pronunciations ending in "*QbjUleIt".

For example, thankest and wrongest, as in "thou thankest me too much" or "wrongst thou not me!", depending on how the words thankest /θæŋkst/ and wrongst /rɑːŋkst/ are pronounced, with the latter dependent on being subject to vowel-forward version of the cot–caught merger.
