Other forms: clans
A clan is an extended family. Your clan might include your parents and siblings, but also your cousins and second cousins, aunts and uncles, and grandparents.
Families that are related to each other, whether through marriage or as distant cousins, are members of the same clan. If you get together with a big family group every summer, you can say you vacation with your clan. In Scotland, a person's clan has a specific name, like "clan MacLachlan." The word comes from the Gaelic clann, "family" or "offspring," with the Latin root planta, "offshoot."
