notch + comparative

用法筆記

Almost always used in fixed comparative phrases: up a notch (improve), down a notch (reduce), a notch above (superior to), several notches better/worse than (much better/worse). Rarely used alone — 'a notch on the scale' is acceptable but less natural than the set phrases.

常見錯誤

His score was a notch.
His score was a notch above average.
💡The set phrase needs the comparison; 'a notch' alone sounds incomplete.
Take it to the next notch.
Take it up a notch.' or 'Take it to the next level.
💡'Notch' follows 'up/down/a notch above'; 'next level' is a different pattern.
