Is the Internet to Blame?

As we spend less time listening to the radio or watching TV and more time online, the latter has the most influence on our day-to-day dialogue.

The fast pace of the internet also means we adopt words much faster than ever before. “Language itself changes slowly, but the internet has sped up the process of those changes so you notice them more quickly,” David Crystal, honorary professor of linguistics at the University of Bangor, told BBC News. You can imagine how much longer it took new words to spread through word-of-mouth than it does today with the internet.

How Slang Spreads on the Internet

Linguistics and anthropologists have studied how slang spreads for decades, but it was only possible to measure with precision once public social media networks emerged.

Platforms help linguists accurately and easily search and record language exchanges. For example, Jacob Eisenstein and his colleagues at the Georgia Institute of Technology examined 30 million tweets from the U.S. to pinpoint the origin of popular slang words and their spread. The image below is the resulting map that shows how terms migrated and their direction of influence.

Slang now moves around within weeks and months instead of years, says Julia Coleman, author of The Life of Slang. “It’s not necessarily that language is changing more quickly, but technologies have developed and they allow the transmission of slang terms to pass from one group to another much more quickly.”

Internet Slang Around the World

The internet impacts the development of language all across the world.

In Ukraine, Svitlana Pyrkalo says the force-quit process of pressing control+alt+delete is known as Дуля (dulya). A dulya is a Ukranian gesture using two fingers and a thumb, used in the same situations in which we‘d give “the finger.” “And you need three fingers to press the buttons,” says Pyrkalo. “So it’s like telling somebody, a computer in this case, to get lost.”

Other countries have their own versions of “LOL.” In France, “mdr” stands for “mort de rire,” meaning dying of laughter. The Swedish write “asg” as an abbreviation of Asgarv, meaning intense laughter. The number 5 in Thailand signifies the letter “h,” so 555 is “hahaha.”

It’s important to note that a lot of popular internet slang comes from African-American Vernacular English (AAVE), a form of English spoken by Black Americans. Often, Black people have conversations online, other people use the words, and they become part of everyday internet speak.

With all of this in mind, let’s review some of the most popular internet slang words, many of which are acronyms and others full words and phrases.

How New Words Make It Into the Dictionary

Once new words have grown and become part of the general lexicon, how do acronyms like “LOL” make it to the dictionary? Longevity.

To make it into the dictionary, the general population must use it and keep using it. Fiona McPherson, Senior Editor, Oxford English Dictionary, says five years is a good length to become eligible for a spot in the big book.

Dictionary editors also look to us when voting on whether a word should have a place in their dictionary. “Dictionaries are fantastic resources, but they are human and they are not timeless,” Language Historian Anne Curzan reminds us. “If you ask dictionary editors, what they‘ll tell you is they’re just trying to keep up with us as we change the language. They‘re watching what we say and what we write and trying to figure out what’s going to stick and what’s not going to stick.”

So, no matter whether you think internet slang vitalizes or destroys language, there’s no denying how revealing it is of the culture that invents and uses it — and the ease with which we adapt our language to new technologies and concepts.
