This book investigates the fundamental nature of nouns, verbs, and adjectives.Mark C. Baker investigates the fundamental nature of nouns, verbs, and adjectives. He claims that the various superficial differences that are found in particular languages have a single underlying source which can be used to give better definitions of these 'parts of speech'. These new definitions are supported by data from languages from every continent. The book thus argues for a formal, syntax-oriented, and universal approach to the parts of speech, as opposed to the functionalist, semantic, and relativist approaches that have dominated the few previous works on the subject.Mark C.
