Particularly significant has been the influence of Nahuatl, especially in the lexicon. However, while in the vocabulary its influence is undeniable, it is hardly felt in the grammar field. In the lexicon, in addition to the words that originated from Mexico with which the Spanish language has been enriched, such as "tomato," "rubber," "chalk," "chocolate," "coyote," "flask," et cetera; the Spanish of Mexico has many Nahuatlismos that confer a lexical personality of its own. It can happen that the Nahuatl word coexists with the Spanish word, as in the cases of "buddy" and "friend," "turkey" and "turkey," "kid" and "boy," "rope" and "rope," etc. On other occasions, the indigenous word differs slightly from the Spanish, as in the case of , which is another type of sandal; , hardware store, , a stone mortar, etc. Other times, the Nahuatl word has almost completely displaced the Spanish, "owl," "cornflour drink," "straw," "cornfield," "green bean," "shack," "kite," etc. There are many "words of indigenous origin" who designate Mexican realities for which there is no Spanish word; "mesquite," "sapota," "jicama," "ixtle," "mockingbird," "husk," , , "crate," "hotplate," "embroidered blouse," "stone for grinding," etc. The strength of the Nahuatl substrate influence is felt less each day, since there are no new contributions. Frequently used Nahuatlismos: "avocado," "peanut," "cocoa," "coyote," "buddy," "chapulin, "gum," "chocolate," "bean," "corn," "huachinango," "turkey," "rubber," "tomato," "Mayan (used for people of African descent)," "rope," "cornfield," "corn husk," "kite," "flask" (per suitcase), "goatee," "buzzard." Moderately frequent Nahuatlismos: "axolotl," "boob" (for female breast), "shack, hut" "youngest child," "owl," "street market," "hardware store," "grass." Purépechismos or Tarasquismos: "sandal," "poncho," "jerkin," ," "bundle of rags, (slang for suit)" "salamander," . Other non-Mexican indigenismos: "flatbread corn," "armchair," "chief, headman," "alligator," "canoe," "coati," "hummingbird," "custard apple," "rags," "guava," "hurricane," "iguana," "jaguar," "crab," "jefen," "parrot," "agave," "corn," "mammee," "peanut," "yam," "rhea," "papaya," "canoe," "puma," "tobacco," " "cassava." The influence of Nahuatl on phonology seems restricted to the monosyllabic pronunciation of digraphs -tz- and -tl- (Mexico: / Spain : ), and to the various pronunciations of the letter -x-, coming to represent the sounds , , , and . In the grammar, one can cite as influence of Nahuatl the extensive use of diminutives: The most common Spanish diminutive suffix is . English examples are –y in doggy or -let in booklet.
