更不用说 (let alone / not to mention)
Meaning
The pattern 更不用说 means 'not to mention' or 'let alone.' It is used to emphasize that if a lesser case is already true, the greater or more extreme case goes without saying.
Unlike 别说 which leads with the more extreme case, 更不用说 places the more extreme case at the end of the sentence. The typical structure is: 连 + A (lesser case) + 都/也 + Verb,更不用说 + B (greater case) + 了. The logic flows as: 'Even A is already the case — not to mention B.' This makes 更不用说 feel more like a natural conclusion or afterthought, building from a stated fact toward an even stronger implication. It is slightly more formal than 别说 and is common in essays, speeches, and persuasive arguments. The variant 更别说 is also widely used and carries the same meaning in a slightly more colloquial tone.
