Get off the couch (5)
I believe the answer is:
arise
'get off the couch' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for arise that I've seen before include "Become apparent" , "W B Yeats: 'I will . . . . . and go now'" , "Originate; stand up" , "Originate; get up" , "Get to one's feet" .)
