Written Taiwanese provides the first comprehensive account of the different ways in which Taiwanese (i.e., the Southern Min language of Taiwan) has been represented in written sources. The scope of the study ranges from early popular writings in closely related dialects to present-day forms of written Taiwanese. The study treats written Taiwanese both as a linguistic and as a socio-political phenomenon. The linguistic description focuses on the interrelation between written units and Taiwanese speech and covers various linguistic subfields, such as Taiwanese lexicography, phonology, and morphosyntax. The socio-political analysis explores the historical backgrounds which have led to different conventions in writing Taiwanese.
