Etymology

It is inherited from Middle English feute, also feaute and later fealtye,[2][3][4] borrowed from Old French feauté, also fealté,[5][3][2][6] from Latin fidēlitās (“faithfulness, fidelity”),[5][7][8] from fidēlis (“loyal, faithful”),[5][8] from fidēs (“faith”),[8][7] from Proto-Indo-European *bheidh- (“to trust, confide, persuade”).[5][7] Merriam-Webster Unabridged and Dictionary.com explain the Old French form with l by the influence of feal (“faithful”),[4][9] and Merriam-Webster Unabridged explains the modern English spelling by Middle French fealté.[4] The Anglo-Norman fedeilté is recorded from the first half of the 12th century, with the phrase for swearing it.[10] The OED compares Old Occitan fealtad,[8] and the word is a doublet of fidelity.[3][11]

Earliest recorded meaning

The act of recognising a vassal's duty to his lord, as feute, about 1300, in Kyng Alisaunder.[8][3][5]

Semantic evolution

The earliest record is of the recognition of the duty, a sense often found in phrases for doing or swearing fealty.[8] The OED's first record of the obligation itself comes later, about 1460, in John Russell's Boke of Nurture.[8] From the early 16th century, in Hyckescorner, the word spread to loyalty of other kinds,[8] and Johnson (1755) gives "duty due to a superior lord; fidelity to a master; loyalty", quoting Shakespeare's "lasting fealty to the new-made king".[12] Merriam-Webster Unabridged now lists faithfulness or allegiance in general as well as the feudal senses.[4]

Timeline

  • c. 1300 – feute, a vassal's recognition of his duty to his lord.[8][3]
  • before 1425 – the spelling fealtye.[3]
  • c. 1460 – the obligation of fidelity of a feudal tenant.[8]
  • c. 1515 – transferred and figurative use.[8]

Meanings

Noun

  1. In feudal society, the fidelity owed by a vassal or tenant to his lord, or the obligation of it.[13][4][8]
  2. An oath or public acknowledgement of that obligation: The barons came to swear fealty to the young king.[4][8]
  3. Faithfulness or allegiance in general: Their fealty to the party survived the scandal.[4][8]
