LINGUA AS DEFINED IS THE ABILITY TO TALK TO THEM THATS AROUND YA. To put it in Texas. I would like to be able to speak to a INUET. and ask. "Seen any white bear?"? Or a Damari hunter and ask, "Eland?". The Towder of Babel is among us every day. The ultimate knowlege in man would be total LINGUA FRANCA.
