Fealty vs. Fidelity

By Jaxson

  • Fealty

    An oath of fealty, from the Latin fidelitas (faithfulness), is a pledge of allegiance of one person to another.

  • Fidelity

    Fidelity is the quality of faithfulness or loyalty. Its original meaning regarded duty in a broader sense than the related concept of fealty. Both derive from the Latin word fidēlis, meaning “faithful or loyal”. In the City of London financial markets it has traditionally been used in the sense encompassed in the motto “My word is my bond”.
