How it's used
交界 describes the physical point or line where two distinct areas meet, often used for borders, districts, or zones. It carries a slightly formal or geographical tone, making it more common in descriptions of maps or urban planning than in casual conversation about small objects. When referring to the specific border between countries or regions, it is frequently used with the names of the two places directly preceding it.

Common mistake
Learners sometimes confuse 交界 with 交叉點, which refers specifically to a crossing or intersection of lines or paths. Use 交界 for regions or territories, and 交叉點 for roads or abstract intersections.
