To begin with, it has nothing to do with archaism, with the salvaging of obsolete words and turns of speech, or with the setting-up of a "standard-English" which must never be departed from. On the contrary, it is especially concerned with the scrapping of every word or idiom which has outworn its usefulness. It has nothing to do with correct grammar and syntax, which are of no importance so long as one makes one's meaning clear, or with the avoidance of Americanisms, or with having what is called a "good prose style." On the other hand it is not concerned with fake simplicity and the attempt to make written English colloquial.
