IPA: /ˈmeɪ.tri.ɑːr.ki/
KK: /ˈmeɪ.tri.ɑːr.ki/
A social system where women, especially mothers, hold the power and authority in the family or community.
In a matriarchy, women often make the important decisions for the family.
Matriarchy is formed from "matri-" (from Latin "mater", meaning mother) and "-archy" (from Greek "archia", meaning rule or government). The term describes a social system where mothers or women hold the primary power and authority.
Think of 'mother' ('matri-') being in charge ('-archy') — that's why matriarchy means a system where women or mothers lead.
