This collection is the fifth volume of selected papers to emerge from Columbia School (CS) linguistics conferences. A radically functionalist approach, CS shares with Cognitive linguistics the view that grammar is composed of form-meaning correspondences. CS views language as a symbolic tool whose structure is shaped both by its communicative function and by the characteristics of its users. The volume includes papers on methodological issues and innovative analyses on English, Spanish, and Mandarin that illustrate the value of the strict application of clearly spelled out theoretical principles to the execution of linguistic analysis. Four of the volume's eleven papers are written in Spanish, and all papers have abstracts in both English and Spanish. An introduction highlights the theoretical and analytical premises of CS, and their differences from and similarities with cognitive-functional approaches. The collection will be of interest to researchers and laymen who aim to understand the role of language in human communication.
