What Is a Glossary? | Definition, Templates, & Examples
A glossary is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader.
Your glossary only needs to include terms that your reader may not be familiar with, and it’s intended to enhance their understanding of your work. Glossaries are not mandatory, but if you use a lot of technical or field-specific terms, it may improve readability to add one.
If you do choose to include a glossary, it should go at the beginning of your document, just after the table of contents and (if applicable) list of tables and figures or list of abbreviations. It’s helpful to place your glossary at the beginning, so your readers can familiarize themselves with key terms prior to reading your work. Remember that glossaries are always in alphabetical order.

Citing sources for your glossary
Glossaries and definitions often fall into the category of common knowledge, meaning that they don’t necessarily have to be cited.
However, it’s always better to be safe than sorry when it comes to citing your sources, in order to avoid accidental plagiarism.
If you’d prefer to cite just in case, you can follow guidance for citing dictionary entries in MLA or APA Style for citations in your glossary. Remember that direct quotes should always be accompanied by a citation.
Additional lists to include in your dissertation
In addition to the glossary, you can also include a list of tables and figures and a list of abbreviations in your thesis or dissertation if you choose.
