Shot cut in ad to go up (6)

I believe the answer is:

ascend

I'm a little stuck... Click here to teach me more about this clue!

'to go up' is the definition.
('ascend' can be a synonym of 'go up')

I cannot understand how the remainder of the clue works.

(Other definitions for ascend that I've seen before include "Take off" , "rise in status" , "Travel upwards" , "Move upwards" , "Mount" .)

I've seen this clue in The Sun.
