merchantry, or a place with a market (sometimes spelled Puxtla or Puxtlan)
See an image that represents pochtlan in the Visual Lexicon of Aztec Hieroglyphs, ed. Stephanie Wood (Eugene, Ore.: Wired Humanities, 2020-present).
The best evidence that Puxtla refers to Pochtlan is found in the Matrícula de Huexotzinco (folio 525 recto), where there is a barrio glossed both "Puxtla" and "pochtlan." See the Visual Lexicon of Aztec Hieroglyphs and search Pochtlan.
puchtlan tenan, teta. = the mother, the father of mechantry. (central Mexico, sixteenth century)
