<P> English has words written without the five conventional vowel letters (A, E, I, O, U); it also has words without spoken vowel sounds . In most languages of the world, all or nearly all lexical words have vowel sounds, and English is no exception; however, rhotic dialects of English (such as most varieties of American English) have words like nurse and word with a syllabic r sound, but these words are written with a vowel letter immediately prior to an r . On the other hand, there are words that are not written with any of the five conventional vowel letters, though they are pronounced with a vowel sound . There also are some interjections and besides onomatopoeia, to ideophones in general, that contain neither vowel sounds nor syllabic r and which are thus spelled without a vowel letter . </P> <P> This article does not cover abbreviations, such as km or ms, nor acronyms . </P> <P> In English, the letter Y can represent either a vowel or a consonant sound, and many Modern English words spell the / ɪ / and / aɪ / sounds with Y; these include by, lynx, my, dry, fly, fry, cry, pry, gym, shy, sky, sly, spy, try, sty, why, wry, hymn, cyst, myrrh, myth, wyrm, crypt, flyby, glyph, gypsy, lynch, nymph, pygmy, rhythm, tryst and syzygy which are vowels in these cases . The longest dictionary words (base forms excluding plurals) with Y the only vowel are rhythm, spryly, sylphy, Sphynx and syzygy . The longest such word in common use is rhythms, and the longest such word in Modern English is the obsolete 17th - century word symphysy .
