Pronunciation

Forms

loyauté f (plural loyautés)[1] Old French lealted, leauté, lealté and loiauté; the spelling loyauté is found in Adenet in 1273.[2][3][4] Middle French loyaulte.[1]

Etymology

It is formed from French loyal + -té, with the Old French suffix that continues Latin -itās, rather than taken from the Medieval Latin lēgālitās of the same meaning (1103).[2][5][6] Wiktionary allows that it may correspond to that Medieval Latin noun.[1] loyal is from Latin lēgālis (“in accordance with the law”), from lēx (“law”).[6][1]

Cognate with Old Occitan leialtat, Spanish lealtad, Portuguese lealdade and Italian lealtà.[4][1]

Earliest recorded meaning

It first appears in the Laws of William the Conqueror (as lealted in the TLFi's dating of 1130), where the GLLF reads it as “legality”;[2][3][4] Littré quotes the phrase testimoine de leauté.[2][3][4] Rey and the Grand Robert date the first form loiauté to about 1080 or the end of the 11th century.[7][5]

Semantic evolution

Like the other derivatives of loyal, it belongs to the vocabulary of chivalry that grew up in the 12th century, and names the quality and conduct of a loyal person.[7] The sense “fidelity to one's word, honour” is found about 1160 in Benoît de Sainte-Maure, while the adjective kept its sense “legal” until the 17th century.[3][6] The antonym déloyauté is also of the 12th century.[7][6] Littré recorded the extension to the quality of a thing, as in the loyalty of someone's conduct (1867).[3]

Littré notes that in the 16th century Théodore de Bèze wanted the first syllable pronounced like loi, while in his own time many said lo-iô-té.[4] English loyalty (about 1400) comes from Old French loialte, beside an earlier Middle English leaute (mid-13th century).[8]
