Cantons of Switzerland the canton of Schwyz. Six of the 26 cantons are traditionally, but no longer officially, called "half-cantons" (, , , ). In two instances (Basel and Appenzell) this was a consequence of a historic division, whilst in the case of Unterwalden a historic mutual association, resulting in three pairs of half-cantons. The other 20 cantons were — and in some instances still are — though only in a context where it is needed to distinguish them from any half-cantons, typically termed "full" cantons in English. The historic half-cantons, and their pairings, are still recognizable in the first article of the
Cantons of Switzerland until the late 15th century. "Ort" was increasingly replaced by "Stand" (plural: "Stände") "estate" about 1550, a term taken to imply liberty and sovereignty. Abolished in the Helvetic Republic, the term was revived in 1815 and remains in use today. The French term "canton" adopted into German after 1648, and then only in occasional use until the early 19th century: prominent usage of "Ort" and "Stand" gradually disappeared in German-speaking Switzerland from the time of the Helvetic Republic. Only with the Act of Mediation of 1803 did German "Kanton" become an official designation, retained in the Swiss Constitution of 1848.
