This work is a reference grammar of the Tzutujjl language spoken in the departments of Solola and Suchitepequez in Guatemala. Tzutujil is one of approximately thirty Mayan languages that are spoken by several million people in Mexico, Guatemala, Belize, and Honduras. All Mayan languages lie within the Meso-American cultural area. Tzutujil belongs to the Greater Quichean branch of the Eastern division of Mayan languages, and it is most closely affiliated with Cakchiquel, Quiche, Sacapultec, and Sipacapa (Campbell 1977; Kaufman 1974, 1976).
