How it's used
Refers specifically to a physical or abstract line marking a division between two areas. It is most commonly encountered in the proper noun 新界, which is one of the three main regions of Hong Kong. Outside of geographical contexts, it is rarely used in daily conversation to mean boundary, as other terms like 範圍 are preferred for abstract limits.

Common mistake
Do not confuse this with the verb 界, which means to cut or scratch. When used as a noun for a boundary, it is almost always paired with the measure word 條.
