This is not the full version; start again (6)
I believe the answer is:
resume
'start again' is the definition.
(resume can mean to start doing something again)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for resume that I've seen before include "American CV" , "Carry on where one left off" , "Re-open" , "Start or take up again" , "Pick up again" .)
