The term 'Big Family' can be described by two crossword solutions: CLAN (4 letters) and TRIBE (5 letters). A CLAN is a group of people united by actual or perceived kinship and descent. It is a group of families or households whose ancestors are believed to have lived in the same area for a long period of time. A TRIBE is a larger group of people, usually with a common language, culture, and history, who share a geographic area and are politically organized. Tribes are often divided into clans, which are smaller groups of people who share a common ancestor.
