The Spanish spoken in rural areas of New Mexico and southern Colorado can be described as a regional type of language made up of archaic sixteenth- and seventeenth-century Spanish; Mexican Indian words, mostly from the Nahuatl; a few indigenous Rio Grande Indian words; words and idiomatic expressions peculiar to the Spanish of Mexico (the so-called mexicanismos); local New Mexico and southern Colorado vocabulary; and countless language items from English which the Spanish-speaking segment of the population has borrowed and adapted for everyday use.
