"arranger of sexual liaisons, one who supplies another with the means of gratifying lust," 1520s, "procurer, pimp," from M.E. Pandare (late 14c.), used by Chaucer ("Troylus and Cryseyde"), who borrowed it from Boccaccio (who had it in It. form Pandaro in "Filostrato") as name of the prince who procured the love of Cressida (his niece in Chaucer, his cousin in Boccaccio) for Troilus. The story and the name are of medieval invention. Spelling influenced by agent suffix -er. The verb meaning "to indulge, to minister to base passions" is first recorded c.1600.
