通知

通知 (tōng zhī) is a noun meaning 'notice' or 'announcement.' It refers to an official or formal communication of information, often used in institutional, organizational, or public contexts.

The character 通 (tōng) means 'to communicate' or 'to pass through,' while 知 (zhī) means 'to know' or 'knowledge.' Together, they convey the idea of conveying knowledge or information to others.

通知 is commonly used in schools, workplaces, and government settings. For example, a teacher might issue a 通知 to inform students about a change in schedule. It can also be used in digital contexts, such as app notifications or emails.
