Aghellican is a critically endangered dialect of the Arraian language belonging to the Irise subgroup of the Amiru branch. It is spoken by a small number of people in the Federal Republic of Arrandaí and is considered one of the rarest surviving varieties of the Arraian language.
Aghellican developed from earlier Irise-speaking communities and is closely related to other dialects such as Gumiese, Sata, Chicho Pidgin, Prahecho, Saidman, Guzulu, and Ago. The dialect preserves a number of archaic linguistic features that have disappeared from most other Amiru varieties, making it of particular interest to linguists and language preservation efforts.
Due to a declining speaker population, language shift toward more widely spoken Arraian dialects, and limited intergenerational transmission, Aghellican is classified as critically endangered. Most remaining speakers are elderly, and the dialect is rarely used in education, media, or public life. Preservation initiatives have been proposed to document its vocabulary, grammar, oral traditions, and cultural heritage.
Despite its endangered status, Aghellican remains an important part of Arrandai's linguistic diversity and cultural history.
