""Language is the key to the world." - When reading this sentence we think: yes, of course. That's right. This statement was as true two hundred years ago as it is today. No, in fact it is even more relevant and more important today than ever before. Modern means of communication and the sheer endless mobility of merchandise, persons and services let individual locations become less and less important. It is rather the network of processes, procedures and flows of merchandise and money that counts today.
But wait a minute: what about "the" language?
