Meanings

Interjection

  1. used to say farewell when leaving or ending a conversation

Noun

  1. an expression or act of saying farewell

Beyond the definition

"Goodbye" is what we say when we leave or when someone else leaves. It marks the end of a meeting, a visit, a call, or a conversation. In many cases, it is polite, warm, and simple. It often suggests, even quietly, that the relationship continues after this moment ends.

Sometimes it is quick and casual, like "Bye!" at the door. Sometimes it is heavy and emotional, like when people separate for a long time or for the last time. You can use it in formal situations, such as ending a business call, and in everyday life, such as leaving a friend's house. People also say it in a deeper sense when speaking about death or loss.
