Learn these acronym examples ASAP

Sometimes we have a lot to say, but little time to say it. That’s where acronyms come in and help speed things up. What exactly is an acronym? It’s a word comprised of the first initials of the other words, which is then pronounced as its own word. Acronyms are created to shorten long phrases and speed up communication, much like abbreviations and initialisms.

While these terms are similar, they do have distinct differences to note. Abbreviations shorten a word or phrase without creating a new word to say (think of “avenue” being abbreviated to “ave.”). Initialisms are words comprised of the first letter of phrases, but you say the individual letters instead of combining them to make a new word (think “RSVP“—you don’t create a new word when reading it aloud). Did you know canola in canola oil is an acronym?

You’ve likely seen these acronyms in everyday life mixed in with common texting abbreviations. But what exactly do they mean? Here’s a quick guide to keep you in the know and help you communicate faster (we also included some common abbreviations and initialisms for reference).
