sooner or later; more or less
Expresses that something will happen regardless of minor differences in degree or timing.
This pattern pairs two opposite adjectives to say 'whether it's A or B, ultimately X'. It emphasizes that the outcome is unavoidable or that the difference doesn't matter. For example, おそかれはやかれ means 'sooner or later', おおかれすくなかれ means 'more or less'. It's a set, somewhat formal expression used mainly in writing or formal speech. You won't hear it in casual conversation, but it's useful for essays, news, and presentations. The pattern is quite fixed; you only use it with a few common pairs like these.
