In Uttering Trees, Norvin Richards investigates the conditions imposed upon syntax by the need to create syntactic objects that can be interpreted by phonology—that is, objects that can be pronounced. Drawing extensively on linguistic data from a variety of languages, including Japanese, Basque, Tagalog, Spanish, Kinande (Bantu language spoken in the Democratic Republic of the Congo), and Chaha (Semitic language spoken in Ethiopia), Richards makes two new proposals about the relationship between syntax and phonology.
