This course presents an introduction to the core areas of linguistics and a discussion of of the fundamental concepts in the study of language. We will explore technical aspects of linguistic theory as well as broader questions about language as a specifically human phenomenon. This online system has been implemented using Moodle, an open source communication system supervised by Pedro A. Willging, from the University of Illinois, Urbana-Champaign, and the tech suport team at the Facultad de Ciencias Exactas, Universidad Nacional de La Pampa. I thank them for their cooperation and technological support :-)
