The most important domain and technical terms that your stakeholders use when discussing the system.
You can also see the glossary as source for translations if you work in a multi-language environment (i.e. in offshore development models).
You should clearly define your terms, so that all stakeholders
- have an identical understanding of these termes
- do not use synonyms and homonyms
- A simple table with columns <Term> and <Definition>
- Potentially more columns for translations
