cajole (v.)

"deceive or delude by flattery," 1640s, from French cajoler "to cajole, wheedle, coax," a word of uncertain origin; perhaps a blend of cageoler "to chatter like a jay" (16c., from gajole, southern diminutive of geai "jay;" see jay (n.)), and Old French gaioler "to cage, entice into a cage" (see jail (n.)). Related: Cajoled; cajoling.
