Word buffs have long known that a remarkable several-syllable word written without any of the five basic vowels (A, E, I, O, U) is the word SYZYGY. No one knows why this particular word should have been singled out for attention. It certainly is not the longest such word: longer examples include, but are not limited to, GYPSYFY, GYPSYRY, and SYMPHYSY. Yet, the fact remains that no one ever heard of these longer words, but everyone knows about SYZYGY.
