IPA: /ˈmeɪ.tri.ɑrk/
KK: /ˈmeɪtriˌɑrk/
A respected woman who is in charge of a family, group, or community, often being the oldest or most influential member.
The matriarch of the family organized the reunion and made sure everyone was invited.
Matriarch is formed from "mater" (meaning mother) and "archon" (meaning ruler or leader). The word describes a woman who is the head or leader of a family or group, emphasizing her role as a mother figure in that position.
Think of a 'mother' ('mater') who is also a 'ruler' ('archon') — that's why a matriarch is a leading mother figure.
