Nonfilial
/ˌnɒnˈfɪliəl/noun
Not relating to or characteristic of a son or daughter; not showing the respect or duty expected toward a parent.
Did you know?Its core comes from Latin *filius* “son” and *filia* “daughter,” the same root family behind words like *affiliate* and *filial*, making it a literal “not-childlike” rejection of kin duty.
