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. A new study, however, suggests that’s not always true. Recently researchers have discovered that there's 23 ancient words that have commonalities with over half of the 700 languages spoken by half of the world's population. This leads them to believe these words date back to at least 15,000 years ago; so during the Ice Age.
