What does the term 'canton' refer to in relation to a flag?

The term 'canton' refers to the upper corner area of a flag, typically located next to the flagpole. This section often contains significant symbols, such as stars or other designs that represent the nation or organization the flag represents. In many flags, especially national flags, the canton is a place where specific emblems or decorations are positioned to convey meaning or identity, making it a prominent and recognizable feature of the flag.

In contrast, the field of the flag refers to the entire background of the flag, while the main stripe pertains to significant horizontal or vertical bands of color that may run across the flag’s surface. The flagpole emblem, if present, typically identifies the flag's allegiance and does not specifically refer to the flag's design elements. Understanding the significance of the canton helps in interpreting the symbols and colors used within flags, especially in contexts such as ceremonies or military procedures.
