Edward Sapir was an early 20th century leader in the field of linguists. He was a leader in American structural linguistics, and one of the creators of the Sapir-Whorf hypothesis. His accomplishments include a substantial series of publications on Nootka and other languages, and his seminal book Language (1921), which is still a leading book in the field. Language an Introduction To The Study Of Speech provides the reader with everything from a grammar-typological classification of languages, as seen in the Chinese tand Nootka languages, to speculation on the phenomenon of Language drift and the arbitrariness of associations between language, race, and culture.
