The word "notice" refers to the act of observing something or becoming aware of it. It can also mean a formal announcement or communication about something important. For example, when you notice a change in someone’s behavior, it indicates that you are aware of that change. In a formal context, a notice could be a written communication that informs people about an event, decision, or other important information.
The word "notice" comes from the Middle English term "notic," which is derived from the Old French "notice," meaning “a being known." It has roots in the Latin word "notitia," which means "knowledge" or "awareness."
