The English name ''Switzerland'' is a compound containing ''Switzer'', an obsolete term for a Swiss person which was in use during the 16th to 19th centuries. The English adjective ''Swiss'' is a loan from French '''', also in use since the 16th century. The name ''Switzer'' is from the Alemannic '''', in origin an inhabitant of ''Schwyz'' and its associated territory, one of the Waldstätte cantons which formed the nucleus of the Old Swiss Confederacy. The Swiss began to adopt the name for themselves after the Swabian War of 1499, used alongside the term for "Confederates", ''Eidgenossen'' (literally: ''comrades by oath''), used since the 14th century. The data code for Switzerland, CH, is derived from Latin ''Confoederatio Helvetica'' ().
