Synonyms & Differences: vs. -은/는커녕
The most common synonym for -(으)ㄴ/는 고사하고 is -은/는커녕. In most situations, they are interchangeable and carry the same meaning of "let alone" or "far from."
Interchangeable Usage
Both patterns are used to contrast an expected outcome with a disappointing reality. -은/는커녕 is generally considered more common in everyday spoken Korean, while -(으)ㄴ/는 고사하고 can sometimes feel slightly more formal or emphatic, but this distinction is minor.
보너스는 고사하고 월급도 깎였어.
보너스는커녕 월급도 깎였어.
(Both mean: "Let alone a bonus, even my salary was cut.")
Nuance
While they can be swapped freely, think of -은/는커녕 as the default, everyday choice. Using -(으)ㄴ/는 고사하고 might add a touch more weight or gravity to your statement, as if you're formally presenting the unfortunate facts.
