How it's used

While 應當 shares the same meaning as 應該, it carries a slightly more formal or emphatic tone. It is frequently used in written contexts or when expressing a moral obligation rather than a simple suggestion. In casual spoken Cantonese, 應該 is overwhelmingly more common.

Examples

You really ought to go and ask him clearly.

Common phrases

Common mistake

Learners often use 應當 in everyday casual conversation where it sounds overly stiff or literary. Stick to 應該 for normal daily interactions to avoid sounding like you are reading from a textbook or a formal speech.
