What's an Acronym?

An acronym is an abbreviation formed from each of the first letters of a descriptive phrase or by combining the initial letters or parts of words from the phrase. An acronym is actually a type of abbreviation. The word comes from Greek, meaning heads of names. The origins of acronyms are a little unclear, but their widespread use in daily life is a relatively modern phenomenon. In more restricted circumstances, however, they have been in use for thousands of years (both the Roman and Hebrew cultures used them).

Here are some examples of acronyms:

As Far As I Know = AFAIK
As Soon As Possible = ASAP
Seek Professional Help = SPH

Their use has become very popular in recent years, especially in e-mail, text messaging, chat rooms and online forums.

Below you will find many acronnyms, sorted alphabetically. If you have an acronym and want to know what it means, and it's not listed here (and many are not) go to the The Acronym Finder or, links below. You can also create your own acronyms at the Systematic Buzz Phrase Generator or The Acronym Liar websites, links below.

Systematic Buzz Phrase Generator

In 1968, Newsweek magazine published a short, but humorous article, How to Win at Wordsmanship. It described the "Systematic Buzz Phrase Projector," a concept developed by Philip Broughton, a (then) 63 year old worker in the US Public Health Service. He must have had a delightful sense of humor.

The Acronym Finder has implemented Broughton's Systematic Buzz Phrase Projector (SBPP if you like) as a fun way of not only randomly generating his buzz phrases, but also (what else?), the corresponding acronyms and abbreviations they form.

To use the SBPP, just make up a 3 digit number and then choose the numbered buzzword from each column. So, if you chose 031, you would get Integrated Reciprocal Flexibility (IRF). Try it for yourself.

Also check out The Acronym Liar...randomized and completely false acronyms at the touch of a button.
