Pike is best known for his distinction between the
emic and the etic. "Emic" (as in "
phonemics") refers to the role of cultural and linguistic categories as understood from within the cultural or linguistic system that they are a part of, while "etic" (as in "
phonetics") refers to the analytical study of those sounds grounded outside of the system itself. Pike argued that only native speakers are competent judges of emic descriptions, and are thus crucial in providing data for linguistic research, while investigators from outside the linguistic group apply scientific methods in the analysis of language, producing etic descriptions which are verifiable and reproducible. Pike himself carried out studies of indigenous languages in
Australia,
Bolivia,
Ecuador,
Ghana,
Java,
Mexico,
Nepal,
New Guinea,
Nigeria, the
Philippines, and
Peru. Pike developed his theory of
tagmemics to help with the analysis of languages from
Central and
South America, by identifying (using both
semantic and
syntactic elements) strings of linguistic elements capable of playing a number of different roles. Pike's approach to the study of language put him outside the circle of the "generative" movement begun by
Noam Chomsky, a dominant linguist in the 20th century, since Pike believed that the structure of language should be studied in context, not just as single sentences, as seen in the title of his magnum opus,
Language in Relation to a Unified Theory of the Structure of Human Behavior (1967). He became well known for his "
monolingual demonstrations." He would stand before an audience, with a large number of chalkboards. A speaker of a language unknown to him would be brought in to work with Pike. Using gestures and objects, not asking questions in a language that the person might know, Pike would begin to analyze the language before the audience. ==Honors==
