How it's used

This term carries a heavy sense of formality and legal weight, often associated with official government positions or courtroom proceedings. Unlike casual promises, it implies a binding commitment that can have serious consequences if broken. It is almost exclusively used in professional or civic contexts rather than personal relationships.

Examples

They are taking their oaths at the Legislative Council today.

Common phrases

to take an oath of office
swearing-in ceremony

Common mistake

Learners often confuse this with general promises like 承諾, but 宣誓 is specifically reserved for formal, public, or legal declarations. Using it for a casual promise to a friend sounds bizarrely stiff and overly dramatic.
