Taiwanese Hangul (Hangul: ; ; ) is an orthography system for Taiwanese Hokkien (Taiwanese). Developed and promoted by Taiwanese linguist (許æ¹德) in 1987, it uses modified Hangul letters to represent spoken Taiwanese, and was later supported by Ang Ui-jin.
Because both Chinese characters and Hangul are both written in the space of square boxes, unlike letters of the Latin alphabet, the use of Chinese-Hangul mixed writing is able to keep the spacing between the two scripts more consistent compared to Chinese-Latin mixed writing. Anecdotally, the system was boosted by in the 1990s as an early attempt to communicate in spoken Taiwanese using the then newly introduced mail servers being implemented at the National Taiwan University.
