One outcome of the Norman Conquest was the making of the English language.... the speech of Alfred and Bede, was exiled from hall and bower, from court and cloister, and was despised as a peasant's jargon... It ceased almost, though not quite, to be a written language. … Now when a language is seldom written and is not an object of interest to scholars, it quickly adapts itself in the mouths of plain people to the needs and uses of life.... it can be altered much more easily when there are no grammarians to protest. During the three centuries when our native language was a peasant's dialect, it lost its clumsy inflexions and elaborate genders, and acquired the grace, suppleness, and adaptability which are among its chief merits.
