The New York Times, July 19, 2005. By Michael Erard. "Among the facts in the new edition of Ethnologue, a sprawling compendium of the world's languages, are that 119 of them are sign languages for the deaf and that 497 are nearly extinct. Only one artificial language has native speakers. (Yes, it's Esperanto.) Most languages have fewer than a million speakers, and the most linguistically diverse nation on the planet is Papua New Guinea. The least diverse? Haiti." | Leia "A language is a dialect with a missionary", resenha da 15a. edição do Ethnologue pelo jornalista dinamarquês Ole Stig Andersen (Danmarks Radio). |
