The expression "see off" means to say goodbye to someone who is leaving or to escort them to their departure point, like a bus or train station, airport, or harbor. It is usually used when someone is leaving for a long trip or journey, and the act of "seeing them off" is a way to show support and affection. For example, you can say "I'm going to see off my friend at the airport" or "We will be there to see off our daughter when she leaves for college." It can also be used in a more metaphorical sense, such as "We need to see off this competitor to stay on top."
