拘禁

1. Origins, structure, and basic meaning

• Structure: 拘禁 is read as こうきん and functions as a noun or する verb for confinement or detention.
• Basic usage: The passive 拘禁された describes being confined, while 不当な拘禁 characterizes the detention itself.

2. Common pitfalls and similar expressions

• Place versus confinement
  • 塔の中に identifies where the person is held; 拘禁 names the restriction of freedom, not the tower.
• Target of protest
  • In 拘禁に抗議する, に marks the measure being protested and 不当な evaluates it as unjust.
