English (language)

English was the language originally spoken in England. It was also spoken over much of Earth. Though there were many speakers of English, it was not always the most common language. In the early 21st century, Mandarin was most widely spoken. (TV: Children of Earth: Day One) It was said to be easier for the Eurozone to know English than to teach the world other languages.

(AUDIO: The Reaping, PROSE: Deceit) Additionally, the English and Americans had different words for the same thing, such as the "bumper" or "fender" of a car. (AUDIO: 1963: The Space Race)
