gringo (n.) Look up gringo at
term for a European or Anglo-American, 1847, from American Spanish gringo "foreigner," from Spanish gringo "foreign speech, unintelligible talk, gibberish," perhaps ultimately from griego "Greek." The "Diccionario Castellano" (1787) says gringo was used in Malaga for "anyone who spoke Spanish badly," and in Madrid for "the Irish." Hence the American Spanish verb engringarse "to act like a foreigner."
