About
界 is a phono-semantic compound where the top component 田 serves as the semantic radical for agricultural fields, and the bottom component 介 acts as the phonetic element while also conveying a sense of being between things. Its original meaning referred to the physical boundaries or dividing lines between plots of farmland. This concrete origin later expanded to encompass abstract concepts such as national borders, specific domains of study, distinct social circles or industries, and ultimately the broader notion of the entire world or universal realm.
