Taiwanese Hangul (Hangul: 대끼깐뿐; Chinese: 臺語諺文; pinyin: Táiyǔ Yànwén; Pe̍h-ōe-jī: Tâi-gí Gān-bûn) is an orthography system for Taiwanese Hokkien (Taiwanese). Developed and promoted by Taiwanese linguist Hsu Tsao-te [zh] 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.
