wheedle (v.) Look up wheedle at Dictionary.com
"to influence by flattery," 1660s, of uncertain origin, perhaps connected with Old English wædlian "to beg," from wædl "poverty" [OED], or borrowed by English soldiers in the Thirty Years' War from German wedeln "wag the tail," hence "fawn, flatter" (compare adulation). Related: Wheedled; wheedling.
