ourselves where languages come from because they just seem to be there: French
in France, English in England, Chinese in China, Japanese in Japan, and so
forth. Yet if we go back only a few thousand years, none of these languages
were spoken in their respective countries and indeed none of these languages
existed anywhere in the world. Where did they all come from? This question is
examined by this site by Exploratorium Magazine.
