Proposal to end the standstill? (6)
I believe the answer is:
motion
'proposal' is the definition.
(proposal at a meeting)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for motion that I've seen before include "Movement or proposal" , "Formal proposal put to a meeting" , "Proposal for action" , "Formal proposal for debate" , "That's debatable" .)
