This feels like a stupid question, but here goes. I'm trying to figure out what language (other than English or any other Western European language) would be useful/respectful to learn a few words of for travel all around Namibia. I understand 50% of the country is of Bantu origin and speak a Bantu language, but there are still many distinct languages among Bantu people, and then there is the array of the other, non-Bantu languages that comprise the other 50%. We will be travelling a circuit, so will be in many areas of the country. Any suggestions for what language to learn a bit of? thanks.
