To reunite means to come together again after being separated. When a family reunites after someone returns from a long trip, they gather together with joy and relief. When childhood friends reunite years later, they reconnect and catch up on all the time that passed.

You might reunite with your classmates at the start of a new school year after summer break, or a lost dog might reunite with its owner after wandering away.

Sometimes people work hard to reunite separated family members, like helping refugees find relatives they lost contact with during war. Other times reunions happen naturally, like when cousins reunite at a family gathering each Thanksgiving.

The word suggests something positive: the happiness of being back together with people or even places you care about. When you reunite with an old friend, there's often excitement mixed with the comfort of picking up where you left off. A class reunion is when former students gather to reconnect years after graduating, celebrating the bonds they once shared.
