The Gaelic language family is divided into distinct branches, including Irish Gaelic and Scottish Gaelic. Scottish Gaelic is a Celtic language spoken along the northwest coast of Scotland and on the Hebrides Islands.
Scottish Gaelic is written in a variation of the Latin alphabet. It also uses characters with diacritic marks, including à, è, ì, ò, and ù, to indicate various aspects of pronunciation. You can type these characters by typing the base character for the letter you want, then selecting the special character from the set of characters which appears.
See Typing Accents and Special Characters for details on typing methods.
