They re invaded for economic reasons, rather than by the spread of English itself, or by the spread of either Swahili or Hausa itself. It happens in different parts of Latin America through Spanish. But when you talk to people in Spain, they re upset about the rise of English in Europe. So many of the languages which are lingua francas in some parts of the world are themselvesvery uncomfortable in other parts of the world. So globalisation is a problem which hits the big as well as the small, but it s the tiny ones that suffer most.
Authenticity relates their language to their culture.
These are all things that make up authenticity. And particularly if it s a very small culture, very few people are involved, then it is really quite unique, because there s no other people like that anywhere, and they know that nobody else knows their language. They know that they re quite distinctive. It s not like English, where you can find a somewhat different English in New Zealand, and then in the United States, and then in Great Britain, and then in Canada. These are languages that can be found no place else but a little patch on the earth, and therefore they realise that to know that, you must be one of them, and to be one of them, you must know that.
