This project focuses on three interrelated domains of endangered cultural knowledge and linguistic expression: • nomenclature, classification and use of plants in Nahuat communities in the municipality of Cuetzalan, Puebla, Mexico; • the creation of objects of daily use from regional flora; • traditional ecological knowledge. It builds upon experiences and trust Amith has developed after three years of lexicographic work: two native speakers have advanced skills in digital recording, transcription, and ethnographic description; three partnering Indigenous collectives will facilitate work in scores of communities throughout the municipality and are building a cultural center to utilize project results in education and outreach.
