2. n. The language of the Icelanders or of their literature. It is the oldest and best-preserved member of the Scandinavian branch of the Teutonic family of languages. In its older form, called Old Norse, it stands as the type of the general Scandinavian speech as first recorded (tenth and eleventh centuries), of which Norwegian, Swedish, and Danish are the modern continental forms. Modern Icelandic dates from the Reformation; it preserves in great part the external form of the Old Icelandic, with considerable changes in pronunciation and vocabulary. Many important historical, poetical, theological, and other works have been written in Icelandic, from the tenth century to the present time. Abbreviated Icelandic
