Early formal specifications of natural language syntax were quite closely connected to the notion of abstract machines for computing them. This provided a very natural means of gauging the relative difficulty of processing various constructions, as well as offering some insight into the abstract properties of the human language faculty. More recently, this approach has been superseded by one in which languages are specified in terms of systems of constraints on the structure of their sentences. This has made complexity results difficult to obtain. This book introduces a way of obtaining such results. It presents a natural and quite general means of expressing constraints on the structure of trees and shows that the languages that can be specified by systems of such constraints are exactly those computable by a particular standard class of abstract machines. Thus the difficulty of processing a construction can be reduced to the difficulty of expressing the constraints that specify it. The technique is demonstrated by applying it to a fairly complete treatment of English within the framework of Government and Binding theory, with the result of showing that its complexity is much less than has heretofore been assumed.

Discover Romanian's thorough treatment of both language and culture makes it an effective learning tool in classroom and individualized settings.

This comprehensive introduction to Romanian for English-speaking students emphasizes communication with a complete treatment of grammar, an extensive vocabulary, and a focus on the four major language skills—listening, speaking, reading, and writing. Cultural information, an integral part of the textbook, is presented both formally, in sections on culture and civilization, and informally, as the setting for dialogues and exercises. Tables of verb conjugations and a glossary round out the book's primary materials.

Straightforward and accessible, Discover Romanian is an essential textbook for all those teaching and learning the language and provides important information for those seeking to understand Romanian culture.
