A sept (/sɛpt/) is a division of a family, especially of a Scottish or Irish family.[1] The term is used in both Scotland and Ireland, where it may be translated as sliocht, meaning "progeny" or "seed",[2] which may indicate the descendants of a person (for example, Sliocht Bhriain Mhic Dhiarmada, "the descendant of Brian MacDermott"). The word may derive from the Latin saeptum, meaning "enclosure" or "fold",[3] or via an alteration of "sect".[4]
