This workbook gives you the chance to use the linguistic principles you''ve been learning to analyze language data. Here you''ll find exercises for practice in 30 natural languages, including popular ones, such as Chinese and Spanish, and threatened or nearly extinct ones, such as Lakota and Wichita, as well as constructed languages like Klingon (from the world of Star Trek) and Na''vi (spoken on Pandora in the movie Avatar). You can hear much of the foreign-language data pronounced by native speakers in audio files on the book''s website.
