means A thin, flat round of unleavened bread made from corn or wheat flour, central to Mexican and Central American cooking and used to wrap, fold, or scoop food.

from From Spanish tortilla, a diminutive of torta, 'a round cake,' which traces back to Late Latin torta, 'a twisted or round loaf' — likely from Latin torquere, 'to twist.' When Spanish colonizers reached the Americas, they borrowed their own little-cake word for the flat maize breads Indigenous peoples had been making for millennia; the Nahuatl name was tlaxcalli. So the Spanish diminutive stuck to something far older than the language that named it.
