Reunited means when two people or groups who were once together are now back together again. It's like being reunited with an old friend from school.
When we say someone was reunited with their family after a long time apart, it usually means they had to leave home for some reason, and then they finally went back to live with them. This can be because of work, education, or even war. For example, a soldier who fought in a war might get reunited with his loved ones when he comes back home. Sometimes, people are also reunited with their family members after being apart due to travel or migration. It's always a happy moment for those involved, as they're now together again and can catch up on lost time.
