"Colonial functionaries had to learn the major language of their territory at a formidable level. A kitchen jargon, good enough for wives, with bad grammar and a master-race pronunciation, was usually preferred by the natives, who did not believe it was possible for a foreigner with a white skin to learn their tongue. Colonial civil servants had to disconcert these natives with a linguistic mastery, including a control of many registers, equal to, or greater than, their own."
