Etymology

It is Middle English loyaltee, borrowed from Old French loialté (“loyalty, fidelity; legitimacy; honesty”), lealté,[2][3][4] from loial (see loyal), from Latin legalis.[2] The earlier Middle English form was leaute (mid-13th century), from the older French form.[2]

Earliest recorded meaning

Faithful adherence to one's promise or oath: about 1400.[5][2]

Semantic evolution

Faithful adherence to the sovereign or lawful government is from 1531.[5] Lawfulness, as of a marriage, is a rare obsolete sense of 1660.[5] The American loyalty oath is attested by 1852.[2][5] The Century Dictionary (1897), quoted in Etymonline, distinguishes allegiance, a matter of principle and conduct, from loyalty, which also implies feeling, enthusiasm and devotion.[2] Brand loyalty and the loyalty card are commercial uses.[3][4]
