A farewell is an occasion when someone says goodbye to another person or group. It's often a formal way to bid each other adieu.
When people leave each other after a visit or event, they might say "farewell" as a polite way of saying goodbye. You can hear it in situations like when friends go their separate ways at the airport, or when colleagues wrap up a project together. In these cases, farewell is used to acknowledge that you won't see each other again for a while, but also to show appreciation and respect for the time you spent together. Farewell might be spoken at weddings, graduations, or any occasion where people are parting ways for an extended period.
A wish of happiness or safety at parting, especially a permanent departure.
Example: He bid farewell to all of his fans.
