Details

The keyword for 侵 is encroach. This kanji refers to the act of gradually intruding upon or infringing on someone else's territory, rights, or boundaries. It carries a sense of slow, creeping invasion—whether physical, as in a military incursion into another country's land, or abstract, as in the erosion of someone's rights or personal space. The nuance emphasizes an unwelcome and often stealthy advance that violates what rightfully belongs to another.
