Favorlang language

Favorlang is an extinct Formosan language closely related to Babuza. Although Favorlang is considered by Taiwanese linguist Paul Jen-kuei Li to be a separate language, it is nevertheless very closely related to Babuza. In fact, the name Favorlang is derived from Babuza. Alternatively, Favorlang may also have represented a dialect of Babuza at an earlier stage, since Favorlang was documented in the mid-17th century, while Babuza was documented only around the turn of the 20th century by Japanese linguists.
