tlachīxquētl.

"For Nahuas, one who is born with the natural gift of wisdom necessary to identify and interpret data related to the body and surrounding environment, and to predict future phenomenon (climatic or other- wise), is called a tlachixquetl (tlachiya [to see, to look or gaze] + quetl [a person]). If not born with these knowledges, at times they can also be acquired through careful study (in situ and/or by formal education), experience, and practice. This type of practitioner is called an ixtlamaquetl (one who knows through experience: ixtli [face, surface, eye] + tla [something] + mati [to know] + quetl [a person]). In our conversations, de la Cruz Cruz emphasized that the tlachixiquetl and ixtlamaquetl rely upon ancestral knowledge, which is usually conveyed through modeling and storytelling."
