How it's used

常理 is often used in formal or semi-formal contexts to anchor an argument in shared human logic. It functions as a standard for what is expected or reasonable behavior in a given situation. When something deviates from this, speakers frequently use the phrase 唔合常理 to express disbelief or to highlight an anomaly.

Examples

Going by common sense, they should arrive on time.
This matter completely defies common sense, why would it be like this?

Common phrases

according to common sense
defies common sense

Common mistake

Learners sometimes confuse 常理 with 常識. While 常識 refers to general knowledge or basic facts that everyone should know, 常理 focuses more on the logical reasoning or conventional expectations behind a situation.
