banishment
A punishment where someone is forced to leave and stay away.
Banishment means forcing someone to leave their home, city, or country as a punishment, with no permission to return. When a person is banished, they must go away and stay away, often forever.
Throughout history, banishment was a common punishment for serious crimes or political threats. Ancient Athens banished citizens through a process called ostracism, where people voted on who should leave the city for ten years. In medieval Europe, kings banished nobles who threatened their power. Being banished meant losing everything familiar: your home, your friends, your community, and often your livelihood.
The word carries a sense of harsh finality and deep loss. Unlike grounding, which ends after a few days, or suspension from school, which lasts a limited time, banishment was often permanent. The banished person became an exile, forced to live far from home with little hope of return.
You might encounter banishment in stories and fairy tales, where a character gets banished from the kingdom for breaking a law or angering a ruler. While banishment isn't commonly used as an official punishment in modern democracies, the word still describes forced separation from a place or group. Someone might say they feel banished from their friend group after a serious disagreement, though this uses the word more loosely than its original meaning.
