Esceosian (is-CI-o-si-an) is an Ugric language, belonging to the Finno-Ugric family. It descended from the old Finno-Ugric languages. Esceosian has evolved from Proto-Esceosian, which was spoken by Esceosian people during the migration period. Its closest relatives are Finnish and Estonian, belonging to the Finnic group of Finno-Ugric languages. Today, owing to Esceosia's past overseas expansion, there are numerous Esceosian-based languages, most notably Norezan Esceosian, American Esceosian and Haitian Creole. An Esceosian-speaking person or nation may be referred to as Esceophone in English.
