Slavoljub Milekic & Steven E. Weisler 
Theory of Language [PDF ebook] 

In this introductory-level linguistics text, Steven E. Weisler and Slavko Milekic develop a theoretically motivated analysis of language with an emphasis on grammar construction and argumentation. They introduce the theory of language, sounds, words, sentences, and meaning, as well as language and the brain.The text is available either in hard-copy form or as a CD-ROM. The CD-ROM presents the text in a dynamic digital learning environment, engaging the user in simulations, demonstrations, hypothesis testing, and theory construction while providing a systematic introduction to linguistic theory. The electronic edition also incorporates the Tree Builder tool for construction and evaluation of phonological, metrical, and syntactic analysis of trees, as well as a word processor, various annotation mechanisms (for example, the ability to create and exchange voice and text memos), import/export capabilities that allow the exchange of different types of information, and an extensive series of interviews with such prominent figures as David Caplan, Noam Chomsky, Lyn Frazier, John Rickford, Tom Roeper, Ivan Sag, and Tom Wasow.
