Renowned linguist Kenneth L. Pike and his coauthors offer three previously unpublished essays that apply theoretical linguistic research to the areas of historical linguistics, cross-cultural communications, and text analysis. "Toward the Historical Reconstruction of Matrix Patterns in Morphology" establishes a comprehensive theory of morphological structure based on a number of languages. "Understanding Misunderstanding as Cross-Cultural Emic Clash" examines the crucial role that language plays in the numerous problems encountered in contacts between people from divergent cultural backgrounds. "The Importance of Purposive Behavior in Text Analysis" explores the centrality of establishing the relationship of reality to what is actually expressed in a text.
