The Washington Post reports on an intriguing new study on "ultra-conserved words," holdovers from our common ancestral tongue:
The traditional view is that words can’t survive for more than 8,000 to 9,000 years. Evolution, linguistic “weathering” and the adoption of replacements from other languages eventually drive ancient words to extinction, just like the dinosaurs of the Jurassic era.
A new study, however, suggests that’s not always true. A team of researchers has come up with a list of two dozen “ultraconserved words” that have survived 150 centuries. It includes some predictable entries: “mother,” “not,” “what,” “to hear” and “man.” It also contains surprises: “to flow,” “ashes” and “worm.”
The existence of the long-lived words suggests there was a “proto-Eurasiatic” language that was the common ancestor to about 700 contemporary languages that are the native tongues of more than half the world’s people.
