更迭

1. Origins, structure, and basic meaning

• Structure: 更迭 is read as こうてつ and is a noun and する verb for removing a person from a position and replacing them in a personnel change.
• Basic usage: Removal from a post appears in 部長が更迭される, while demanding replacement appears in 監督の更迭を求める.

2. Common pitfalls and similar expressions

• Personnel replacement
  • Rather than replacing an object, it belongs to personnel contexts involving managers, coaches, officials, or others holding a position.
• Difference from 解任
  • 解任 focuses on dismissing someone from their present duty, while 更迭 presents a personnel change in which that person is removed and the post is changed or filled by a successor.
