Three-letter vowel-less word describes a word in the English language which contains three letters, none of which is generally recognized as a symbol representing a vowel. These words will usually contain voiced vowels that are represented or implied by the consonant letters.

Examples:

  • cwm -- A steep bowl-shaped hollow on a hill or mountain, for example the Western Cym on Mount Everest. (This is a Welsh word sometimes found as a loanword; more usually, it has been adapted and spelled in a more usual English manner as comb or combe. It should be noted that Welsh orthography considers w to be a vowel.)
  • nth -- Relating to an unspecified ordinal number: ten to the nth power. Highest; utmost: delighted to the nth degree. Pronounced "enth".
