Word History

Etymology

probably borrowed from Spanish Nacho, hypocoristic form of the personal name Ignacio

Note: According to a story that apparently first appeared in the San Antonio Express on May 23, 1954 ("Nacho's? Natch!", by Clarence D. LaRoche, p. 3H), the dish was devised in 1940 by Ignacio "Nacho" Anaya García (1895-1975), a waiter (in other versions a maitre d' or chef) at a restaurant in Piedras Negras, Mexico. As related by LaRoche and in later versions, the story has stock elements of a culinary origin myth: late in the day a waiter or chef is pressed to come up with food to satisfy hungry customers and with limited ingredients left in the kitchen invents a new dish. Similar stories purport to explain the origins of other eponymous dishes, as the Reuben sandwich, Buffalo wings and Caesar salad. Though a print connection between "Nacho" Anaya and nachos is relatively early—predating the popularity of the snack outside south Texas—the first citations for nacho, in 1948 and 1949, make no reference to him.
