A semantic inventory, an organized network of observations on the lexical structure of Huichol, is presented. Each entry includes a name form or lemma, its pronunciation if not clear from the lemma form, part of speech, and examples to illustrate its range of inflections. The discussion of semantics begins with a syntactic framework for the definition using a typical sentence, followed by the definition proper, phrased in terms of elements of the typical sentence as examples of the semantic range of actants. There is a brief equivalent in Spanish -- or sometimes in the regional dialect of rural Nayarit -- and a statement of the diathesis or mapping between semantic actants and grammatical constituents, with semantic restrictions among actants spelled out. The entry also contains references to other words whose definitions share the same structure as the one being defined (not necessarily synonyms), the values of all the lexical functions, and finally the cross references to that word from other parts of the inventory. A summary in English reviews the strategy and form of the inventory, the writing system, abbreviations, and special symbols used, and the lexical functions cited. (Author/JK)
