Did you know?
- In Japanese social dynamics, admitting one is 役に立たない is often used as a strategic form of modesty to avoid being given more responsibility or to deflect praise.
- The word 役 in this phrase literally refers to a 'role' or 'duty', as in a part played in a play or a specific job function. When you say you are useless, you are linguistically stating that you cannot play your assigned role.
- If you want to say something is completely useless or 'good for nothing', you can use the more intense expression 役立たず. Adding 'zu' to the end turns the phrase into a noun that functions as a derogatory label for a person.

- 最近、何も役に立たないなと感じてるんだよ。Lately, I feel like I am useless at everything.

- こんなことばかりで、俺は役に立たん。I'm useless with just these things.
