Reviving long-forgotten knowledge
For most of us, the languages that we are — primarily or exclusively —exposed to as a child, becomes our native languages as an adult. This, of course, does not come as a surprise, nor as breaking news. It is almost always the case that, from the moment children are born until they start school, they are raised in a natural environment where they are constantly in interaction with the languages of their parents, and, if different, the languages of their society. Thus, their birth languages as infants become their dominant languages as adults. However, for some children, namely adoptees, this is not the case.
