According to one etymological theory, the culinary meaning of taco derives from its plug meaning as employed among Mexican silver miners, who used explosive charges in plug form consisting of a paper wrapper and gunpowder filling. Indigenous origins for the culinary word taco are also proposed. One possibility is that the word derives from the Nahuatl word tlahco, meaning half or in the middle, in the sense that food would be placed in the middle of a tortilla.
