The Dinh language (Tiếng Đinh; Indralan: 丁語 Dīngyǔ) is the native language of the Dinh people. It is the most widely spoken language in Kimlien, and several speakers are also to be found in Indrala. Dinh is a Gao-Indralan language, belonging to the Southern branch of the family, together with Indralan, Phra, and other languages. Dinh was formerly written in a modified set of Gao characters, but it is currently written exclusively in a modified Selucian (Latin) script, with additional diacritics for tones.
