The Xinkan language family is the only pre-colonial, non-Mayan language group in Mesoamerica. This is a truly multilingual dictionary, offering forms, functions, and information in four Xinkan languages (Chiquimulilla, Guazacapán , Jumaytepeque, and Yupiltepeque), Spanish, and English, alongside brief grammar  sketches in both English and Spanish. This dictionary will be useful for scholars of Mesoamerica and language learners, and an invaluable resource for the Xinkan community.
