Non-stop outside after vote cast (7)
I believe the answer is:
eternal
'non-stop' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for eternal that I've seen before include "One being forever" , "unchanged by time" , "non-stop" , "Valid for all time" , "'Lasting forever, unending (7)'" .)
