English words without vowels

English orthography typically represents vowel sounds with the five conventional vowel letters ⟨a, e, i, o, u⟩, as well as ⟨y⟩, which may also be a consonant depending on context. However, outside of abbreviations, there are a handful of words in English that do not have vowels, either because the vowel sounds are not written with vowel letters or because the words themselves are pronounced without vowel sounds.

Words without written vowels

There are very few lexical words (that is, not counting interjections) without vowel letters. The longest such lexical word is tsktsks,^[1] pronounced /ˌtɪskˈtɪsks/. The mathematical expression nth /ˈɛnθ/, as in delighted to the nth degree, is in fairly common usage.^[2] Another mathematical term without vowel letters is ln, the natural logarithm. A more obscure example is rng /ˈrʌŋ/, derived from ring by deleting the letter ⟨i⟩. Vowelless proper names from other languages, such as the surname

In the Middle English period, there were no standard spellings, but ⟨w⟩ was sometimes used to represent either a vowel or a consonant sound in the same way that Modern English does with ⟨y⟩, particularly during the 14th and 15th centuries. This vocalic ⟨w⟩ generally represented /uː/,^[3][4] as in wss ("use").^[5] However at that time the form ⟨w⟩ was still sometimes used to represent a digraph ⟨uu⟩ (see W), not as a separate letter. In modern Welsh, "W" is simply a single letter which often represents a vowel sound. Thus words borrowed from Welsh may use ⟨w⟩ this way, such as:

• The crwth^[6] (pronounced /ˈkrʊθ/ or /ˈkruːθ/, also spelled cruth in English) is a Welsh musical instrument similar to the violin.^[7]

He intricately rhymes, to the music of crwth and pibgorn.^[8]
