Glossary of Terms

We know that for a newcomer to Extinction Rebellion our resources and newsletters can appear full of jargon, acronyms and nonsense. First of all, we sincerly apologise for this. Jargon is useful shorthand within a group but can be unhelpful to new rebels and so we have created this page to help!

See also the Glossary for new rebels in the Rebel Starter Pack!.

Feel free to add new entries or add in terms you have come across which you do not understand. This is by no means a complete list.

  • Mandate - Each role and circle within XR has a mandate, and this tells those in that role or circle what they can do and lets others know what that role or circle is responsible for.
