頑がん是ぜ

noun

distinction between right and wrong

Almost exclusively used in the negative phrase 頑是ない (or 頑是がない), meaning 'innocent' or 'unable to tell right from wrong', especially of young children. The standalone noun is rare.

• まだ頑がん是ぜない子こ供どもだから、悪わる気ぎはなかったんだ。

  He's still a child who can't tell right from wrong, so he didn't mean any harm.
