Hello @David Whitworth ,

well if I understand correctly, you can find the description of these specific priorities in Settings -> Issues -> Issue Attributes -> Priorities. Priorities are well described there.

However, you can adjust these prirorities absolutely by your liking. You can adjust the name, description and icons of these. You can also create absolutely new priority. 

Let me know if that helped you.

Hello @David Whitworth , here are some of the definitions we use. Here is a nice write up on Organizing issues with priority to optimize delivery 
 

• Blocker - Need to stop other work to get this one done asap.
• Critical - Needs to be the top priority for the current sprint
• Major - Important functionality that helps a large number of users
• Minor - Default Priority, typical day to day work
• Low - Low priority
