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!

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.

Organisational Terms

Affinity groups ought to be self contained, having their own wellbeing rebels, support rebels, media rebels etc.
  • Community Group - A group brough together by their identity, this could be their faith, culture, occupation or really anything! Out community groups include XR Grandparents, XR Muslims, XR Boatdwellers, XR Doctors etc
  • DNA - The things that make us XR. These include our Principles & Values, our Self-Organising System, our Ways of Working etc. Essentially our DNA brings together all the things that we, as XR, fundamentally agree on.
  • The Hive - The Hive is the widest circle in the XRUK organism. It is made up of representatives from each Nation and Region of the UK as well as some from the UK Support structure. It aims to hold XR UK’s shared purpose within the global XR movement, supporting it to achieve its 3 demands in the UK.
  • 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. Mandates are typically written as a statement of purpose (why the role or circle exists) and a list of accountabilities (what those rebels are responsible for).
  • Self-Organising System - Is our system of organising. It includes how we make decisions, define roles and structure ourselves. The Self-Organising System is dynamic and evolving as we learn what works and what doesn't.
