Definition
An acronymous word is one formed from the initial letters of other words and pronounced as a word itself, like NASA or LOL. It's distinct from initialisms, which are also formed from initials but pronounced letter by letter (like FBI). Acronyms often become so common we forget their origins. Think of it like a shortcut code that becomes the standard way to say something longer. For example, 'ASAP' started as 'as soon as possible'.
