委任

1. Origins, structure, and basic meaning

• Structure: 委任 (いにん) is an action noun, used with する, for entrusting a task or authority to another person.
• Basic usage: 手続きを担当者に委任した marks the entrusted procedure with を and the recipient with に, while 代理人への委任 forms a noun phrase for delegation directed to a representative.

2. Common pitfalls and similar expressions

• Delegated matter and recipient
  • In 契約の手続きを委任する, what is transferred is responsibility for the procedure; 担当者に and 代理人への identify the recipient. The person is not what gets delegated.
