Fealty is an old-fashioned and somewhat literary word that refers to intense loyalty or fidelity to a person, group, etc. More narrowly, fealty refers to the fidelity of a vassal or feudal tenant to their lord.

// Authors who inspire such fealty can guarantee a publisher good sales, no matter the quality of the books they write.

// Kneeling before the entire court, the knight pledged his fealty to the king.

“[Director, Denis] Villeneuve’s ‘Dune’ movies deserve admiration if only for their fealty and ambition; the filmmaker’s respect for [Frank] Herbert’s source material radiates from every frame of movies that feel as massive as they are minutely orchestrated.” — Ann Hornaday, The Washington Post, 28 Feb. 2024

In The Use of Law, published posthumously in 1629, Francis Bacon wrote, “Fealty is to take an oath upon a book, that he will be a faithful Tenant to the King.” That’s a pretty accurate summary of the early meaning of fealty. Early forms of the term were used in Middle English in the early 14th century, when they specifically designated the loyalty of a vassal to a lord. Eventually, the meaning of the word broadened. Fealty can be paid to a country, a principle, or a leader of any kind, though the synonyms fidelity and loyalty are more commonly used. Fealty comes from the Anglo-French word feelté, or fealté, which comes from the Latin noun fidēlitās, meaning “fidelity.” These words come ultimately from fidēs, the Latin word for “faith.”
