You Won’t Believe If There’s One Hidden Rule: Is a Vowel Really a Vowel? When you were in elementary school, learning your ABCs, you were told that vowels—A, E, I, O, U—are the building blocks of speech and language. But did you ever pause to ask: Is a vowel really a vowel? That might sound absurd at first, but there’s a surprising truth behind this deceptively simple question. In this article, we explore a hidden rule about vowels that challenges common assumptions and reveals just how fundamental (and subtle) vowel sounds really are in linguistics and everyday communication. ### What Is a Vowel, Anyway?
