Control the English language? Impossible, every day new words and phrases pop up(usually in gaming circles and on forums), I bet before 1995 almost none of you would have shouted "OWNED!" when someone fell over or off something. Take the word Google for example it was a noun and is also now a verb, e.g. "I'm gonna google cloverfeild and see what the hell its all about." It isn't a modern thing either, "I'm going to hoover the carpet" Hoover is a make of vacuum cleaner, It's all to do with the laziness of the tounge, "I'm going to google..." is easier to say than "I'm going to go on google and search for..." although they mean the same things. The invention of new words and phrases is what makes languages as diverse as they are today, If new words were never invented we would stuck with saying things like: "He was killed by a person paid to commit the act" (we can thank Shakespeare for the word assassinated) If new words were never created we would be trapped by an inability to express ourselves fully and quickly.
