Here is a site listing the numbers from 1 to 10 in more than 4500 languages.
It is interesting to browse through this massive catalog of languages, all of them representing a separate culture, history and the identity of a people who were proud, who talked, laughed and sang in that language.
And while many of these languages still exist, much more is lost forever. Thousands of languages will never be spoken again.
Of course much of this is the natural progression of human history, ever more mobile people mixing, spreading and suffocating languages and cultures. But on the other hand it represents the catastrophic loss of much of what has been established before. Songs never to be sung again. Stories never again to be shared.
