A number of derivations have been given to the word Mexico, as mexitli, navel of the maguey; metl-ico, place amidst the maguey; meixco, on the maguey border; mecitli, hare; metztli, moon; amexica, or mexica, you of the anointed ones. The signification spring, or fountain, has also been applied. But most writers have contented themselves by assuming it to be identical with the mexi, mexitl, or mecitl, appellation of the war god, Huitzilopochtli, to which has been added the co, an affix implying locality; hence Mexico would imply the place or settlement of Mexica, or Mexicans. This war god, Huitzilopochtli, as is well known, was the mythic leader and chief deity of the Aztecs, the dominant tribe of the Nahua nation.
