Half of All Languages Come from One Root Language. How it Spread Is Something of Debate

Compelling evidence makes the case for both the Steppe and Anatolian Hypotheses. 

 

The sheer variety of languages on Earth is dizzying in their array and divergence. What’s more intriguing, is that about half of them spoken today by some three billion people, come from a single root language, used thousands of years ago. Hindi, Bengali, Persian, English, German, Spanish, and Greek, all come from the same root, known as Proto-Indo-European (PIE). In total, 400 languages and dialects originate from PIE.


German linguist August Schleicher reconstructed its vocabulary back in 1868. He wondered what PIE sounded like. So he created a fable called “The Sheep and the Horses.” Over the years, as more information has been unearthed about the Bronze Age cultures who spoke this language, the fable has been updated. Of course, scholars argue over what PIE actually sounded like. Nothing is definitive. But we have an approximation.

Here’s the latest recording of spoken PIE performed by University of Kentucky linguist Andrew Byrd:

Big Think Edge
  • Push Past Negative Self-Talk: Give Yourself the Proper Fuel to Attack the World, with David Goggins, Former NAVY SealIf you've ever spent 5 minutes trying to meditate, you know something most people don't realize: that our minds are filled, much of the time, with negative nonsense. Messaging from TV, from the news, from advertising, and from difficult daily interactions pulls us mentally in every direction, insisting that we focus on or worry about this or that. To start from a place of strength and stability, you need to quiet your mind and gain control. For former NAVY Seal David Goggins, this begins with recognizing all the negative self-messaging and committing to quieting the mind. It continues with replacing the negative thoughts with positive ones.
