something that is a little blackened or smoked (see Molina)
Auh in iuh conitoa, quilmach niman no ic oneoac, in quauhtli, quimontoquili: onmotlaztiuetz in tleco, ommotlecomaiauh, oc iehoatl no vellalac: ipampa in iuiio cuicheoac, cuichectic. = And thus do they say: It is told that then flew up an eagle, [which] followed them. It threw itself suddenly into the flames; it cast itself into them, [while] still it blazed up. Therefore its feathers are scorched looking and blackened. (central Mexico, sixteenth-century)
