1. A group, a company, a party, a body, a troop, a crowd, or a bunch: A band of students brought their grievances before the dean of the university.
2. Orchestras, an ensemble, groups: Two different musical bands played until midnight last evening.
3. A binding, a ribbon, a sash, a belt, a collar, a girdle: Daria's hair was held in place by a velvet band.

Dark bands of clouds were forming on the horizon indicating the coming of a rainstorm.

1. To unite, to join, to consolidate; to gather as a group: If the students can band together, they are convinced that they can give their complaints greater strength.
2. To attach a tag or an identification marker to an animal so its movements can be tracked: The veterinarian was careful when she was banding Mary's dog.

Amazingly, when the dog was lost as a result of a storm, it was found by Alanna some miles away and because it was banded, she was able to return the dog to Mary.
