An Introduction to Language Files

Since its inception more than forty years ago, Language Files has grown from a collection of materials designed simply as a supplement for undergraduate courses into a full-fledged introductory textbook. The scope of the text makes it suitable for use in a wide range of courses, while its unique organization into instructor-friendly files allows for tremendous flexibility in course design.

Language Files was originally the idea of Arnold Zwicky, who was among its first authors. Since the first edition, many editors have contributed to the development of Language Files; the current edition is the result of this cumulative effort.

Changes in the Current Edition

In the 13th edition, we have revised, clarified, and updated many of the existing files and accompanying exercises. Additionally, we have adopted throughout the book the use of the singular they when referring to a generic person whose gender is unknown or irrelevant.

In addition to these global changes, the following chapters have undergone significant revision or changes.
