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 fid─ôlis, 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”.
