What Does The Abbreviation A.K.A. or AKA Mean?

Curious about why you sometimes see the term a.k.a and aka used interchangeably? Wondering which one is correct, or if you have been writing it all wrong? No worries, both are correct as long as you stay consistent, and we’ll explain those differences below so you can decide which might be best to use, and in which scenario.  

The Evolution of AKA

When the phrase also known as was first abbreviated, the letters were separated by periods, signaling that this was indeed an abbreviation and not a word in its own right. As a.k.a. became more commonly used, the periods within the abbreviation were dropped. In fact, aka is widely preferred over a.k.a and even the Merriam-Webster and Oxford English dictionaries list it as aka within their example sources. It also doesn’t resemble any other common English word so it works well as a standalone when used as aka. 

You may find some professors or writing instructors prefer one way over another, and in that situation, always do what your instruction dictates for assignments or work. Even MLA and APA formatting doesn’t specifically specify one over the other and accepts either use – allowing writing instructors to dictate what they prefer. But for personal use, you can use whichever you are most comfortable with.

How to Pronounce AKA

Whether you are reading a.k.a or aka, it is pronounced the same way. The pronunciation is ay-kay-ay and enunciates the three letters separately and not as one word, which means it is not an acronym but just an abbreviation. 

How to Use AKA

We’ve established that you can use both abbreviations either with or without periods and there is no one correct answer. But, did you know you can use either capital or lowercase letters? As stated previously, either is considered correct, but stay consistent with its use. 

AKA Sentence Examples

As mentioned, you have quite a few options to choose from when determining which is your go-to preference. Whether you use A.K.A, AKA, a.k.a, or aka you can’t go wrong unless you decide to intermix them. Take a look at these examples to see AKA in use:

In these days of every-man-for-himself-ism, the guy who takes over is the one who isn’t afraid to break the rules and stand out—like Steven Yeun (a.k.a. Glenn on The Walking Dead), dressed here in the season’s most sophisticated, crisply tailored, workplace-ready tweed suits. (GQ Magazine)

When Not to Use AKA

Although it may be fairly obvious when you can use the abbreviation, there are some hard and fast rules of when NOT to use it in academic writing. For informal writing, it is acceptable for use in a variety of situations, as explained above, but you need to take care when sticking to more technical publications.  What’s not okay in academic contexts is the informal use of aka to introduce an ad-hoc alternative term purely to describe/characterize something – such as, for example:

Houston’s new Astrodome, aka. the Eighth Wonder of the World. ( This Day in Sports)

In Conclusion

If you have ever been a bit stressed about the use of aka and its proper form, you don’t have anything to worry about as all forms are generally accepted. However, since even well-published dictionary sources use the aka style, you might want to follow suit. Be sure to share to help anyone else who might be stressing!
