How it's used

This term is formal and primarily appears in written news reports or literary contexts rather than daily speech. It carries a sense of solemnity or dramatic weight, often used to describe someone making a firm, public commitment or a promise that is difficult to break. Using it in casual conversation will sound overly dramatic or like you are quoting a newspaper headline.

to vow to remain steadfast

Common mistake

Learners often mistake it for a common verb like 講 or 承諾, but it is much more specific to formal oaths or public declarations. It is not used for simple promises like telling a friend you will arrive on time.
