Documented Nahuatl words in the Spanish language (mostly as spoken in Mexico and Mesoamerica) include an extensive list of words that represent (i) animals, (ii) plants, fruit and vegetables, (iii) foods and beverages, and (iv) domestic appliances.
Many of these words end with the absolutive suffix "-tl" in Nahuatl. This word ending—thought to be difficult for Spanish speakers to pronounce at the time—evolved in Spanish into a "-te" ending (e.g. axolotl = ajolote). As a rule of thumb, a Spanish word for an animal, plant, food or home appliance widely used in Mexico and ending in "-te" is highly likely to have a Nahuatl origin.
