Book excerpt: I believe one way to help master a scientific discipline is to master its vocabulary. I have created this glossary for that reason. In the beginning, I used this glossary to help students in my introductory class learn relevant sociological terms that had a direct impact on their successful learning of material presented in that course. It was such a success in my introductory class, that I now use it in all of my sociology courses. In addition to being quizzed on chapter material for each textbook, I also quiz my students over 15 to 30 words from the glossary for each chapter module. I believe, and students agree, that the aforementioned practise leads to a better understanding of sociology on their part, and too, a greater depth of sociological understanding. It is not easy to compile a glossary of sociological terms, concepts, and processes because the discipline is a living discipline unlike some other scientific areas of study. For instance, geologists might discover more components of a rock than previously thought, but the rock is still a rock and has not changed. Sociology on the other hand, by being a living discipline is always evolving-terms, theories, and processes come and go as the discipline adapts to the changing social world. Because of this, this glossary is ever-changing.
