late 13c., "to rub down a horse," from Anglo-Fr. curreier "to curry-comb a horse," from O.Fr. correier "put in order, prepare, curry," from con- intens. prefix + reier "arrange," from a Gmc. source. The surviving sense of curry favor is c.1510, altered by folk etymology from curry favel (c.1400) from O.Fr. correier fauvel "to be false, hypocritical," lit. "to curry the chestnut ('fawn-colored') horse," which in medieval French allegories was a symbol of cunning and deceit.
"spice," 1681, from Tamil kari "sauce, relish for rice."
