IPA: /ˌmætrɪˈlɪniəl/
KK: /mætrɪˈlɪniəl/
Connected to family lineage that is traced through the mother's side rather than the father's side.
In some cultures, property and family names are passed down in a matrilineal way.
Matrilineal → It is formed from "mater" (from Latin, meaning mother) and "linealis" (from Latin, meaning of or belonging to a line). The word "matrilineal" refers to a lineage or descent that is traced through the mother.
Think of 'mother' ('mater') as the source of lineage — that's why matrilineal means tracing descent through the mother.
