understanding language

I think I'm well on my way to discovering how I can understand languages that I have never studied. While this feat has probably been performed by many others I am in no way a neurologist so what I'm saying here may not be 100 percent accurate. In my anthropology class I read an article entitled broca's area, wernicke's area, and other language processing areas in the brain, which can be found online. In this article it states "it is the left hemisphere that formulates and understands the meaning of words and sentences, while the right hemisphere interprets the emotional connotation of these words". The right hemisphere must be easy to train the more languages one learns. Thus the more languages one knows the easier it is to grasp the emotional connotation of languages one does not know. Therefore while the interpreter does not have the strength of the left hemisphere, as one isn't able to understand the meaning of words and sentences, one can still grasp the general gist of the conversation through the understanding of the right hemisphere.%
