primus inter pares

Primus inter pares is a Latin phrase meaning first among equals. It is typically used as an honorary title for someone who is formally equal to other members of their group but is accorded unofficial respect, traditionally owing to their seniority in office.

Various modern figures such as the prime minister in parliamentary systems, the president of the Swiss Confederation, the chief justice of the United States, the chief justice of the Philippines, the archbishop of Canterbury of the Anglican Communion, the chair of the Federal Reserve in the United States and the ecumenical patriarch of Constantinople of the Eastern Orthodox Church fall under both senses: bearing higher status and various additional powers while remaining still merely equal to their peers in important senses.
