Glossary module
From MoodleDocs
The glossary activity module allows participants to create and maintain a list of definitions, like a dictionary.
Glossary can be used in many ways. The entries can be searched or browsed in different formats. A glossary can be collaborative or entries only made by the teacher. Entries can be put in categories. The autolinking feature, will highlight any word in the course which is located in the glossary. Autolinking can be turned off in the quiz module. It is possible to import and export entries from one glossary to another. Site wide (global) glossaries can be created that work in all courses. An entry can be linked to more than one key phrase.
