I was recently reading a news article in which I saw a photograph of the German leader speaking to the Chinese leader, who was wearing translation headphones. The thought crossed my mind, "I wonder if they both speak English." It is, after all, the lingua franca. Therein lies my amusement. "Lingua franca" is a Latin phrase which literally refers to the French language but nowadays is understood to stand for English, by which the Germans can talk to the Chinese about the Koreans.
O, Tower of Babel!
