implore (v.)

c. 1500, from Middle French implorer and directly from Latin implorare "call on for help, beseech, beg earnestly," with a literal sense probably of "plead tearfully, invoke with weeping," from assimilated form of in- "on, upon" (from PIE root *en "in") + plorare "to weep, cry out," a word of unknown origin. Related: Implored; imploring; imploringly; imploration.
