This new edition is concerned primarily with the learned vocabulary of English - the words borrowed from the classical languages. It surveys the historical events that define the layers of vocabulary in English, introduces some of the basic principles of linguistic analysis, and is a helpful manual for vocabulary discernment and enrichment. The new edition has been updated with a discussion of the most recent trends of blending and shortening associated with texting and other forms of electronic communication and includes a new classification of the types of allomorphy.
