IPA: /ˈdʒɛrənəˌkræt/
KK: /ˈdʒɛrənˌoʊkræt/
A person who is part of a ruling group made up of older individuals, often holding power due to their age rather than their abilities.
In the gerontocracy, decisions were often made by those who had been in power for decades.
Gerontocrat is formed from "geronto-" (from Greek "geron", meaning old man) and "-crat" (from Greek "kratos", meaning power or rule). The word describes a person who holds power or authority due to their age, specifically an elder or senior figure in governance.
Think of 'geron' meaning 'old man' and 'kratos' meaning 'power' — a gerontocrat is someone who has power because they are older.
