Lackey
early 16th century: from French laquais, perhaps from Catalan alacay, from Arabic al-qā'id ‘the chief’.
wiktionary
Borrowed from Middle French laquais, which is probably (via Old Occitan lacai?) from Spanish lacayo, itself perhaps from Italian lacchè and Greek λακές(lakés), from Turkish ulak. Another possibility is through French, from Catalan alacay, from Arabic اَلْقَاضِي (al-qāḍī, “magistrate”). See French laquais.
etymonline
lackey (n.)
1520s, "footman, running footman, valet," from French laquais "foot soldier, footman, servant" (15c.), a word of unknown origin; perhaps from Old Provençal lacai, from lecai "glutton, covetous," from lecar "to lick." The alternative etymology is that it comes via Old French laquay, from Catalan alacay, from Arabic al-qadi "the judge." Yet another guess traces it through Spanish lacayo, from Italian lacchè, from Modern Greek oulakes, from Turkish ulak "runner, courier." This suits the original sense better, but OED says Italian lacchè is from French. Sense of "servile follower" appeared 1580s. As a political term of abuse it dates from 1939 in communist jargon.
