What does canton mean?
A canton is a territorial subdivision of a country — essentially a small state or province within a larger federation. Its most famous use today is to describe the twenty-six semi-sovereign member states that make up Switzerland, each retaining its own constitution, legislature, and considerable autonomy over matters such as policing, taxation, and education. Historically, the term was also applied to administrative districts in France, Belgium, Luxembourg, and other European nations, though many of those uses have fallen away or been replaced by other terminology. Canton carries a second, quite different meaning in heraldry and flag design: there it denotes the upper corner of a shield or flag, typically the upper hoist quarter — the position occupied by the star-spangled blue rectangle on the flag of the United States, known formally as the union or canton. Derived from a Romance root meaning 'corner' or 'edge', the word conveys the idea of a defined portion carved from a larger whole. It remains essential vocabulary for anyone discussing Swiss politics, federalism, or flag terminology.
nounA canton is a territorial subdivision of a country, especially one of the constituent states of the Swiss Confederation; it can also mean a square division in the upper corner of a flag, as on the flag of the United States.
- A territorial or administrative subdivision of a country, most notably one of the constituent states of Switzerland, but also used historically for similar divisions in France, Belgium, and elsewhere.
- (Heraldry/vexillology) The upper corner of a shield or flag, particularly the upper hoist quarter, as in the blue field bearing stars on the United States flag.
"The Swiss Confederation is made up of twenty-six cantons, each with its own constitution and government."
"Geneva became a member of the Swiss Confederation as its newest canton in 1815."
"On the American flag, fifty white stars are arranged within the blue canton in the upper hoist corner."
Standard plural form; no irregularities.
"The mountainous cantons of central Switzerland have preserved their traditions for centuries."
Every Swiss canton keeps its own army, police force, and even its own constitution — Switzerland isn't really one country so much as a federation of 26 mini-republics that agreed to share a currency and a name.

Etymology of canton
The word 'canton' entered English in the late sixteenth century, borrowed either directly from French or through Italian 'cantone'. Its ultimate root is the Latin 'canto', meaning 'corner' or 'edge' — the same Latin word that gives English 'canto' (a section of a poem), 'cantle' (a piece cut off), and, more distantly, terms related to singing such as 'chant' and 'cantata'. The sense evolved naturally: a corner or edge of a territory becomes a defined district or subdivision. The heraldic sense — the corner of a shield or flag — preserves this original geometric meaning almost exactly.
Usage notes
The plural 'cantons' is standard. In everyday usage, the word is strongly associated with Switzerland; when used for other countries' subdivisions it often sounds slightly archaic or technical. In vexillology (the study of flags), the term has a precise technical meaning distinct from its political sense.
