seventh-generation descendant; great-great-great-great-great-grandchild
A highly specific genealogical term referring to a descendant seven generations removed. Extremely rare in everyday language; mostly encountered in historical or family record contexts.
According to the family tree, he seems to be the seventh-generation descendant of that warlord.
The term is composed of 仍 (still, again, repeatedly) and 孫 (grandchild). The exact historical derivation is uncertain, but it follows the pattern of other generational terms like 玄孫 (great-great-grandchild).
