IYKYK: The Acronyms You Need to Know | StyleBlueprint.com

Share with your friends!

Do you keep seeing clusters of letters over and over again on the internet? Do you continually scratch your head and wonder What does that mean? Acronyms are such an IYKYK kind of thing. (IYKYK = If you know, you know.) I am here to unwrap many of the oft-used abbreviations permeating our vernacular from text conversations to work emails. And, I’ll give a Grammar Shape-Up Series explanation of each acronym. Watch the short explanation video below, and read on!

The term “abbreviation” is the umbrella term for all of our shortened words or phrases, but it covers a lot … from Dr. (short for Doctor) to Dec (short for December) to Rly (short for really) to LOL (short for laugh out loud). An acronym is one type of abbreviation. Acronyms are usually in the form of initialisms, which is when a phrase is represented by the first letter of each word that makes it up. We’re here to tell you that this is a hotly debated topic among linguists. Stay with me.

Some reputable style guides (like my friends: the Oxford English Dictionary and Encyclopedia Brittanica) generally criticize using “acronym” to refer to a word that is not pronounceable. In other words, it is just initialism when the words are pronounced as separate letters. (Examples: NFL, National Football League; and ABC, American Broadcasting Company). A true acronym, to the purists, creates a new word from letters (examples: NATO, North Atlantic Treaty Organization; and NASA, National Aeronautics and Space Administration). See how we say the letters in NFL and CBS, but we say the words NATO and NASA? But what about the abbreviation for As soon as possible? Some would say it like ay-sap, and others, A.S.A.P. Some think the line is fine between an acronym and an initialism.

To make things more interesting, some abbreviations are an acronym and an initialism combined. Examples: JPEG, Joint Photographic Experts Group; and UNESCO, United Nations Educational, Scientific and Cultural Organization. For these, we use a combo of individual letters and a pronounceable word made from initials. Jay Peg. You Nesco. When we read NAACP aloud, most automatically say the Double-A, which adds another element to this acronym.

Allie Wall is a lifelong and careerlong linguist, professor of English and textbook author. I asked for her two favorite acronyms, and she told me scuba and snafu without hesitation. Now, I know what you’re thinking …”snafu is an ACRONYM!?” Yes. Yes, it is. “Many people don’t know that snafu was used in WWII and is derived from the phrase Situation Normal: All F***ed Up!” Allie explains. “The popular TV show ‘M.A.S.H.’ popularized this acronym.” M.A.S.H. is another acronym for Medical Army Surgical Hospital. Allie continues, “A lot of acronyms formed from military slang. AWOL is another good one. Absent without leave.”

For the sake of clarity, I am defining an acronym as letters commonly typed or spoken that combine initials from a larger grouping of words. Whether the acronym reads as a word or as the individual letters is not important here. These things are shortened for a reason, so let’s dive into some interesting and commonly used acronyms.

JIC – Just In Case“Here’s my address, JIC.”

OMW – On My Way!Just typing this acronym in a text auto-generates “On my way!”, which is likely too enthusiastic for how you really feel about where you are going.“My neighbor stopped to talk, but I’m On my way! now.”

One that we have heard a lot recently is BIPOC (often pronounced bye-pock). Black, Indigenous and People Of Color. According to the New York Times, this acronym was first seen on Twitter in 2013, and Google Trends shows a spike in May of this year, coinciding with the growing Black Lives Matter movement. But its purpose has garnered some debate.

TBH, I just hope you all have learned one or two acronyms that you won’t have to Google and a little bit of nerdy history with me today. See you on the next episode!
