expression, i-adjective
useless; worthless; silly; trivial
Describes something or someone as utterly lacking value, often with a dismissive or exasperated tone. Can refer to objects, actions, or people.
そんな益体もない話はやめよう。
Let's stop this pointless talk.
彼は益体もないことでいつも怒っている。
He always gets angry over trivial things.
無駄 means 'wasteful' or 'futile', focusing on lack of utility or efficiency. 益体もない is more about inherent worthlessness or silliness, often with a subjective, dismissive nuance.
つまらない means 'boring' or 'trivial', but is milder and more common. 益体もない carries a stronger sense of contempt or exasperation.
The phrase 益体もない is composed of 益体 (yakudai), meaning 'benefit' or 'use', and the negative ない. The exact origin of 益体 is uncertain, but it is likely a compound of 益 (benefit) and 体 (form/appearance), suggesting something that has no beneficial form or substance.
