About
The character "界" is composed of the semantic component "田", representing a field, and the phonetic and semantic component "介", which denotes a boundary or separation, thus originally referring to the dividing lines between cultivated lands. Its meaning broadened from concrete physical borders to include abstract demarcations, such as domains of knowledge, social spheres, or entire realms like the world, reflecting a conceptual shift from agricultural limits to generalized boundaries in classification and geography.
