There is no true English "word" without a vowel, because besides the classic vowels A, E, I, O, U, the letter Y can be a vowel (and in diphthongs, W). Some utterances, such as grrr, pffft and zzz may be written without a vowel but they are not true words. The word crwth is sometimes found in English dictionaries, but it is a Welsh word using the Welsh alphabet, in which W may be the only vowel in a syllable.
Words with Y as a vowel include: gyp, cry, rhythm, syzygy
Words of Welsh origin (where the W is used instead of Y) include:
- "crwth," which is a musical instrument
- "cwm," which is a hollow in a mountain
Word forms without vowels:
- Interjections (onomatopoeia), such as brr, hmm, psst, shh, tsk, and zzz.
- The numerical term "nth" (an unspecified ordinal)
- The slang word "pwn" (meaning and sometimes pronounced as "own," or as "pone," and referring to a position of dominance, control, or humiliation). The missing vowel is still pronounced in either case.
- Acronyms and initialisms, such as DMV or BRB
