About
The character "界" is structurally composed of "田", indicating a field, and "介", which conveys the idea of a boundary or separation, together forming the original concept of a demarcated area. Initially denoting the physical borders between cultivated plots, its meaning gradually expanded to refer to territorial limits and geographical divisions. Over time, this concrete sense of a boundary was applied metaphorically, allowing the character to represent various abstract realms and domains, such as in the context of social, professional, or natural worlds, while retaining its fundamental association with defined spaces and separation.
