Every word was a new word at some point. The people of England used to speak some version of Celtic, until the Angles and the Saxons invaded in the fifth and sixth centuries and imposed Anglo Saxon. Then their cousins in France invaded again in 1066 and imposed a fund of French terms on top of the Anglo Saxon language, which now, nearly a thousand years and a trip across the Atlantic later, gives us American English.

The Museum of the Portuguese Language is in Sao Paulo, Brazil, home of the largest concentration of Portuguese speaking people in the world.
