Note to readers: This language will be explained in several "lessons", like a high school textbook. Please follow all of the lessons. Xïlusia is a language isolate spoken on Cartays Island (500km east of Seychelles). Like Serbian, it is digraphic, written in either the Latin or Shavian alphabets. There are three dialects: Eastern, Northern, and Southern. The Eastern dialect is tonal, and all three dialects feature declension, conjugation, and mood.
