Re: Ngugi wa Thiong?o: Weep not, Child
Numbers of languages and dialects are crucial.
With languages, some will inevitably suffer neglect and wizen away. Mary LA has reliably informed us that Kenya has 65 languages, and South Africa has 11 official ones. Now, not even the best organised, richest country in the West (e.g. Sweden, where I live) could cope, in sheer volume, with such large numbers of languages.
You have to have a lingua franca or one national language or, at the most, two (e.g. Finland) or three (e.g. Belgium). Otherwise the country remains fragmented and tribal. You can blame the European imperialists of the 19th century for insensitively drawing the borders between the present-day African countries. But you cannot live in a poor country, a country where there is constantly the threat of internecine tribal warfare, with 65 languages at the level of education, commerce and everyday communication, never mind culture.
It's a marvellous situation for linguists who come, examine a language, then go away again. But most ordinary people aren't linguists. They want to communicate on everyday matters. The reason that India works linguistically is because, despite the enormous numbers of languages, most official inter-regional communication occurs in Hindi or English.
Again, with Xhosa, if there are 16 dialects, you can set up a hotel for visiting comparative linguists. But with such a fragmented language, I presume that someone has had to make decisions as to which is the standard or standardised dialect, that is then used officially.
Britain and Sweden both have lots of dialects (some very strong!) and versions of the language. But there is more or less one accepted national version for each country, used for standard communication and literature.
There must be an element of realism employed. When South Africa shook off the yoke of apartheid, it was no doubt a great and liberating idea to have 11 national languages. But as with the European Union (which has about 22) the sheer volume of paperwork and translation becomes crazy. So in Brussels, the only languages used for most communication are English, French and German.
