What words are used here that have new meanings?

In Gilead the meanings of words are changed to their opposites, as in Orwell's Newspeak, in an effort to restructure the way people are allowed to think about their world. For example, the Gileadean rhetoric of 'Aunts', 'Angels', 'Salvagings' takes words with reassuring emotional connotations and distorts them into euphemisms for the instruments of oppression.
