"Before" refers to a time that occurs earlier than a specified point or event. It is often used to describe past events, actions, or conditions that have taken place prior to a certain moment. For example, one might say, "I ate breakfast before going to work," indicating that breakfast happened earlier in the day. In various contexts, "before" can also denote a sequence of events. In storytelling, it helps establish a timeline, allowing readers to understand what happened prior to the main narrative. In everyday conversation, it aids in clarifying the order of actions, such as "I called you before I left the house."
