It is important that we start by trying to define our terms. Please do not define race by physical appearance alone. Race is so much more complex than what someone looks like. Often times races live in specific regions of the world. But where someone lives does not determine race either.
Numerous races live in Africa.
So the term African is not a very specific term to describe race. Language is also an important component of race, but it can not be taken as the only determining factor. People of all races speak English, for example. So language in this case does not relate directly to race. The same can be said of culture.
