noun
all one's relatives; kith and kin
A somewhat formal or literary term encompassing both blood relatives and relatives by marriage. Often used in contexts discussing family ties or obligations.
六親眷属が集まって新年を祝った。
All the relatives gathered to celebrate the New Year.
The term originates from Buddhist and classical Chinese texts, where 六親 refers to six categories of close relatives (father, mother, elder brother, younger brother, wife, child) and 眷属 means 'family dependents' or 'household'. The exact derivation is uncertain, but the compound is used in Japanese to mean all of one's relatives.
