Antropological Linguistics

Ethnography: descriptive study of a particular human society. Contemporary ethnography is based almost entirely on fieldwork. The ethnographer lives among the people who are the subject of study for a year or more, learning the local language and participating in everyday life while striving to maintain a degree of objective detachment. He or she usually cultivates close relationships with “informants” who can provide specific information on aspects of cultural life. While detailed written notes are the mainstay of fieldwork, ethnographers may also use tape recorders, cameras, or video recorders. Contemporary ethnographies have both influenced and been influenced by literary theory

Linguistic ethnography (LE): is a theoretical and methodological development orientating towards particular, established traditions but defining itself in the new intellectual climate of late modernity and post-structuralism.

The most representatives in linguistic ethnography are Edward Sapir, Benjamin Lee Whorf, and Franz Boas.
Sapir propuso una visión alternativa del lenguaje en 1921, afirmando que el lenguaje determina el pensamiento, de forma que cada lengua lleva aparejada una forma de pensar. La idea de Sapir fue adoptada y desarrollada durante los años 1940 por Whorf y finalmente se convirtió en la hipótesis de Sapir-Whorf.
