sept

This term describes a specific kinship structure within Gaelic societies, denoting a smaller family group that shares a common ancestor but remains a subordinate division of a larger clan. It carries a strong connotation of ancestral lineage and regional identity, often used in genealogical research to trace precise familial branches.

Because it refers to a distinct social unit, the word is used as a standard countable noun. It is primarily encountered in historical, anthropological, or heraldic contexts rather than in general modern conversation.
