The Evolution of "Two" in the Indo-European Language Family

The Indo-European language family includes most of the languages of Europe as well as many languages in Asia. There is a long research tradition that has shown, though careful historical comparison, that languages spanning a huge linguistic and geographical range, from French to Greek to Russian to Hindi to Persian, are all related to each other and sprung from a common source, Proto-Indo-European. One of the techniques for studying the relationship of the different languages to each other is to look at the similarities between individual words and work out the sound changes that led from one language to the next.

This diagram, submitted to Reddit by user IronChestplate1, shows the word for two in various Indo-European languages. (The “proto” versions, marked with an asterisk, are hypothesized forms, built by working backward from historical evidence.) The languages cluster around certain common features, but the words are all strikingly similar, especially when you consider the words for two in languages outside the Indo-European family: iki (Turkish), èjì (Yoruba), ni (Japanese), kaksi (Finnish), etc. There are many possible forms two could take, but in this particular group of languages it is extremely limited. What are the chances of that happening by accident? Once you see it laid out like this, it doesn’t take much to put *dwóh and *dwóh together.

From Snoopy to Shark Bait: The Top Slang Word in Each State

There’s a minute, and then there’s a hot minute. Defined as “a longish amount of time,” this unit of time is familiar to Alabamians but may stir up confusion beyond the state’s borders.

It’s Louisianans, though, who feel the “most misunderstood,” according to the results of a survey regarding regional slang by PlayNJ. Of the Louisiana residents surveyed, 72 percent said their fellow Americans from other states—even neighboring ones—have a hard time grasping their lingo. Some learned the hard way that ordering a burger “dressed” (with lettuce, tomato, pickles, and mayo) isn’t universally understood, nor is the phrase “to pass a good time” (instead of “to have” a good time).

After surveying 2000 people (with proportional numbers from each state), PlayNJ created a map showing the top slang word in each state. Many are words that are unlikely to be understood beyond state lines, but others—like California’s bomb (something you really like) and New York’s deadass (to be completely serious)—have spread well beyond their respective borders thanks to memes and internet culture.

Hawaiians are also known for their distinctive slang words, with 71 percent reporting that words like shaka (hello) and poho (waste of time) are frequently misunderstood. Shark bait, one of the state’s more colorful terms, refers to tourists who are so pale that they attract sharks.

Check out the full list below and test your knowledge of regional slang words with PlayNJ’s online quiz.

New 'Eye Language' Lets Paralyzed People Communicate More Easily

The invention of sign language proved you don't need to vocalize to use complex language face to face. Now, a group of designers has shown that you don't even need control of your hands: Their new type of language for paralyzed people relies entirely on the eyes.

As AdAge reports, "Blink to Speak" was created by the design agency TBWA/India for the NeuroGen Brain & Spine Institute and the Asha Ek Hope Foundation. The language takes advantage of one of the few motor functions many paralyzed people have at their disposal: eye movement. Designers had a limited number of moves to work with—looking up, down, left, or right; closing one or both eyes—but they figured out how to use these building blocks to create a sophisticated way to get information across. The final product consists of eight alphabets and messages like "get doctor" and "entertainment" meant to facilitate communication between patients and caregivers.

This isn't the only tool that allows paralyzed people to "speak" through facial movements, but unlike most other options currently available, Blink to Speak doesn't require any expensive technology. The project's potential impact on the lives of people with paralysis earned it the Health Grand Prix for Good at the Cannes Lions International Festival of Creativity earlier in June.

The groups behind Blink to Speak have produced thousands of print copies of the language guide and have made it available online as an ebook. To learn the language yourself or share it with someone you know, you can download it for free here.
