sixth-generation descendant; great-great-great-great-grandchild
A formal genealogical term for a descendant six generations removed. Rare in everyday conversation; typically encountered in historical or family-registry contexts.
He is said to be a sixth-generation descendant of that warlord.
The kanji 昆 means 'descendant' or 'elder brother' and 孫 means 'grandchild'. The combination is a conventional Sino-Japanese term for a sixth-generation descendant, likely derived from classical Chinese genealogical terminology.
