This book, continuously in print since 1983, has become a classic Spanish reference book, widely used in classrooms across the United States. Linguist and folklorist Rubén Cobos, now in his nineties, has been diligently working on revisions for the past decade. Much expanded—the number of pages has increased by seventy—this revised edition will assume its place as the most authoritative reference on the archaic dialect of Spanish spoken in this region.

This linguistic exploration delves into the language as it is spoken by the Hispanic population of New Mexico and southern Colorado.
