Meaning

verb influence or urge by gentle urging, caressing, or flattering

originBorrowed from French cajoler, probably a blend of Middle French cageoler (“chatter like a jay”) (from gajole, dialectal diminutive of geai (“jaybird”)) + Old French gaioler (“entice into a cage”), which is from Medieval Latin gabiola, from Late Latin caveola (whence English caveola), diminutive of Latin cavea (“cage, coop, enclosure, stall”). More at cage, cave, cavum, cavus, and jail.
