fidelity

fidelity allegiance fealty loyalty

These nouns denote faithfulness. Fidelity implies the unfailing fulfillment of one's duties and obligations and strict adherence to vows or promises: fidelity to one's spouse. Allegiance is faithfulness considered as a duty: “I know no South, no North, no East, no West, to which I owe any allegiance᠁ The Union, Sir, is my country” (Henry Clay). Fealty, once applied to the obligation of a tenant or vassal to a feudal lord, now suggests faithfulness that one has pledged to uphold: swore fealty to the laws of that country. Loyalty implies a steadfast and devoted attachment that is not easily turned aside: loyalty to an oath; loyalty to one's family.
