IPA: /ˈpeɪ.tri.ɑrk/
KK: /ˈpeɪtriˌɑrk/
A man who leads a family, group, or community, often seen as a father figure or elder.
In many cultures, the patriarch is responsible for making important decisions for the family.
Patriarch is formed from "patri-" (from Greek "patria", meaning father or family) and "-arch" (from Greek "archon", meaning ruler or leader). The word refers to a male leader or father figure within a family or group.
Think of a 'father' ('patri-') who is also a 'leader' ('-arch') — that's why a patriarch is a father figure who leads.
