This fourth volume on Missionary Linguistics focuses on lexicography. It contains a selection of papers derived from the Fifth International Conference on Missionary Linguistics held in Mérida, Yucatán (Mexico), 14th–17th March 2007. As with the previous three volumes (2004, on general issues, 2005, on orthography and phonology, and 2007 on morphology and syntax), this volume looks at the lexicographical production of missionaries in general, the influence of European sources, such as Ambrogio Calepino and Antonio de Nebrija, translation theories, attitudes toward non-Western cultures, trans- and interculturality, semantics, morphological analysis and organizational principles of the dictionaries, such as styles and structure of the entries, citation forms, etc. It presents research into languages such as Maya, Nahuatl, Tarasco (Pur’épecha), Lushootseed, Equatorian Quechua, Tupinambá, Ilocan, Tamil and Southern Min Chinese dialects.
