noun, masculine/θomˈpantli/plural: zompantlis
in some Mesoamerican civilizations, a wooden rack or palisade used for the public display of human skulls
Borrowed from Classical Nahuatl tzompantli (“skull rack”), of debated composition. Perhaps from tzontli (“hair, head”) (compare tzontecomatl (“head, skull”)) + pantli (“flag, banner”), or simply (“row”).
