Reading the definition of 任務 from 明鏡国語辞典, I found:
その人に課せられた、果たさなくてはならないつとめ。
This seems like 課す (which means to impose a task or tax) in potential and passive form, but I dont understand who it is that is supposed to "be able to 課す". Could someone explain?
I found a definition for 課せられる in weblio which I understand.
主に、果たすべきものとして引き受けさせられること、(責任・責務を負わせられること、などを意味する表現。)
Does this have any relationship with 課す, or should I just learn 課せられる as it's own thing?
