The English Word That Hasn’t Changed in Sound or Meaning in 8,000 Years

One of my favorite words is lox,” says Gregory Guy, a professor of linguistics at New York University. There is hardly a more quintessential New York food than a lox bagel—a century-old popular appetizing store, Russ & Daughters, calls it “The Classic.” But Guy, who has lived in the city for the past 17 years, is passionate about lox for a different reason. “The pronunciation in the Proto-Indo-European was probably ‘lox,’ and that’s exactly how it is pronounced in modern English,” he says. “Then, it meant salmon, and now it specifically means ‘smoked salmon.’ It’s really cool that that word hasn’t changed its pronunciation at all in 8,000 years and still refers to a particular fish.”

How scholars have traced the word’s pronunciation over thousands of years is also really cool. The story goes back to Thomas Young, also known as “The Last Person Who Knew Everything.” The 18th-century British polymath came up with the wave theory of light, first described astigmatism, and played a key role in deciphering the Rosetta Stone. Like some people before him, Young noticed eerie similarities between Indic and European languages. He went further, analyzing 400 languages spread across continents and millennia and proved that the overlap between some of them was too extensive to be an accident. A single coincidence meant nothing, but each additional one increased the chance of an underlying connection. In 1813, Young declared that all those languages belong to one family. He named it “Indo-European.”

Today, roughly half the world’s population speaks an Indo-European language. That family includes 440 languages spoken across the globe, including English. The word yoga, for example, which comes from Sanskrit, the language of ancient India, is a distant relative of the English word yoke. The nature of this relationship puzzled historical linguists for two centuries.

In modern English, well over half of all words are borrowed from other languages. To trace how language changes over time, linguists developed an ingenious toolkit. “Some parts of vocabulary are more stable and don’t change as much. The linguistic term [for these words] is ‘a core vocabulary.’ These are numbers, colors, family relations like ‘mother,’ ‘father,’ ‘sister,’ ‘brother,’ and basic verbs like ‘walk’ and ‘see,’ says Guy. “If you look at words of that sort in different languages, it becomes fairly clear which ones are related and which ones are not. For example, take the English word for number two, which is dva in Russian and deux in French, or the word night, which is nacht in German and noch in Russian.”
