How it's used

This idiom functions as a fixed phrase to emphasize that a conclusion is inevitable or common knowledge. It carries a slightly informal and dismissive tone, suggesting that the answer is so apparent that even asking about it would be redundant. While the character for Gwai is sometimes written as 桂, the version using 貴 is also common in written Cantonese.

Common mistake

Learners often mistake 阿貴 for a specific person, but it is a generic placeholder name similar to John Doe in English. Do not attempt to use it to refer to an actual person named Gwai, as the phrase is strictly idiomatic.
