Tagalog (ta-GA-log) is the national language of the Republic of the Philippines. It is a member of the Western group of Malayo-Polynesian languages.
Tagalog is written in the Latin alphabet. It may also use characters with diacritic marks, including á, à, â, é, è, ê, í, ì, î, ó, ò, ô, ú, ù, and û, to indicate certain aspects of pronunciation. These marks are not required, but are included in certain lessons because they can be helpful to language learners.
The simplest method is to use the character suggestions. To do so, type the base character for the letter you want, then select the special character from the set of characters which appears.
The other method is to use the virtual keyboard with the layout set to Tagalog. When this virtual keyboard is active, holding down the Ctrl and Alt keys at the same time will provide access to special characters. Capital letters are available by holding down the Shift key as well.
See Typing Accents and Special Characters for details on both typing methods.
