from Named after a real person: Ignacio "Nacho" Anaya, a maître d' in Piedras Negras, Mexico, near the Texas border. The well-attested story is that around 1940 a group of hungry diners (often said to be U.S. military wives) arrived after the kitchen had closed, and Nacho improvised by frying tortilla pieces, topping them with cheese and jalapeños. They called the creation "Nacho's especiales" — Nacho's specials — and the name stuck, shortened to "nachos." The nickname "Nacho" is itself a common Spanish pet form of Ignacio.
