On Sunday, we are having the whole clan over to watch the Dallas Cowboy football game. ( That is using the word clan in it's meaning as members of a family or people connected in some way, such as a group that work together.)
My Irish ancestors belonged to the clan of Suilabahn. Today the clan name would be called Sullivan. A clan is sort of like a tribe, only the members are related.
There were a clan of people gathered in front of the accident scene.
There was a clan of children at the fireworks stand.
