Read the excerpt from "politics and the english language" by george orwell. probably it is better to put off using words as long as possible and get one's meaning as clear as one can through pictures or sensations. afterwards one can choose—not simply accept—the phrases that will best cover the meaning, and then switch round and decide what impressions one's words are likely to make on another person. this last effort of the mind cuts out all stale or mixed images, all prefabricated phrases, needless repetitions, and humbug and vagueness generally. which best describes george orwell's purpose and the way he achieves it in this excerpt?
