Jeju has historically had no written language. Two recently devised standard orthographies are currently in use: a system created in 1991 by scholars of the Jeju Dialect Research Society ( ), and a system promulgated by the provincial government in 2014. Both systems use the Korean alphabet Hangul with one additional letter , which was used in the Middle and Early Modern Korean scripts but is now defunct in written Korean. Similar to the modern Korean script, Jeju orthographies have morphophonemic tendencies, meaning that transcribing the underlying morphology generally takes precedence over the surface form. The two orthographies differ largely because they are based on different morphological analyses of the language, especially of the verbal paradigm, as seen in the example below.
