The 1970 Academy dictionary designates the taco origin as onomatopoeia of tac: a piece of wood, metal or any other material short and thick that might fit in any hole; a tissue cylinder, paper or something alike. It is also defined as something light to eat out of the regular meal hours.
No matter which is the correct origin of this word, evidently the taco was a very popular food among the inhabitants of North America, later adapted to the food taste of the Spaniards and obviously to the Creoles and Mestizo who later formed the Mexican nation. Its permanency comes from centuries ago and has been integrated to the Mexican people food through their history not only during their wars and crisis but also in their victories and success.
